How to Become a 1000 Year Old Vampire

This is based on a concept we developed at the Vancouver Rationalists meetup.

Different experiences level a person up at different rates. You could work some boring job all your life and be 60 and not be much more awesome than your average teenager. On the other hand, some people have such varied and so much life experience that by 30 they are as awesome as a 1000 year old vampire.

This reminds me that it's possible to conduct your life with more or less efficiency, sometimes by orders of magnitude. Further, while we don't have actual life extension, it's content we care about, not run time. If you can change your habits such that you get 3 times as much done, that's like tripling your effective lifespan.

So how might one get a 100x speedup and become like a 1000 year old vampire in 10 years? This is absurdly ambitious, but we can try:

Do Hard Things

Some experiences catapult you forward in personal development. You can probably systematically collect these to build formidability as fast as possible.

Paul Graham says that many of the founders he sees (as head of YC) become much more awesome very quickly as need forces them to. This seems plausible and it seems back up by other sources as well. Basically "learn to swim by jumping in the deep end"; people have a tendency to take the easy way that results in less development when given the chance, so the chance to slack off being removed can be beneficial.

That has definitely been my personal experience as well. At work, the head engineer got brain cancer and I got de-facto promoted to head of two of the projects, which I then leveled up to be able to do. It felt pretty scary at first, but now I'm bored and wishing something further would challenge me. (addendum: not bored right now at all; crazy crunch time for the other team, which which I am helping) It seems really hard to just do better without such forcing; as far as I can tell I could work much harder than now, but willpower basically doesn't exist so I don't.

On that note, a friend of mine got big results from joining the Army and getting tear gassed in a trench while wet, cold, exhausted, sleep deprived, and hungry, which pushed him through stuff he wouldn't have thought he could deal with. Apparently it sortof re-calibrated his feelings about how well he should be doing and how hard things are such that he is now a millionaire and awesome.

So the mechanism behind a lot of this seems to be recalibrating what seems hard or scary or beyond your normal sphere. I used to be afraid of phone calls and doing weird stuff like climbing trees in front of strangers, but not so much anymore; it feels like I just forget that they were scary. In the case of the phone there were a few times where I didn't have time to be scared, I needed to just get things done. In the case of climbing trees, I did it on my own enough for it to become normalized so that it didn't even come up that people would see me, because it didn't seem weird.

So tying that back in, there are experiences that you can put yourself into to force that normalization and acclimatization to hard stuff. For example, some people do this thing called "Rejection Therapy" or "Comfort Zone Expansion", basically going out and doing embarrassing or scary things deliberately to recalibrate your intuitions and teach your brain that they are not so scary.

On the failure end, self-improvement projects tend to fail when they require constant application of willpower. It's just a fact that you will fall off the wagon on those things. So you have to make it impossible to fall off the wagon. You have to make it scarier to fall off the wagon than it is to level up and just do it. This is the idea behind Beeminder, which takes your money if you don't do what your last-week self said you would.

I guess the thesis behind all this is that these level-ups are permanent, in that they make you more like a 1000 year old vampire, and you don't just go back to being your boring old mortal self. If this is true, the implication that you should seek out hard stuff seems pretty interesting and important.

Broadness of Experience

Think of a 1000 year old vampire; they would have done everything. Fought in battles, led armies, built great works, been in love, been everywhere, observed most aspects of the human experience, and generally seen it all.

Things you can do have sharply diminishing returns; the first few times you watch great movies is most of the benefit thereof, likewise with video games, 4chan, most jobs, and most experiences in general. Thus it's really important to switch around the things you do a lot so that you stay in that sharp initially growing part of the learning curve. You can get 90% of the vampire's experience with 10% of his time investment if you focus on those most enlightening parts of each experience.

So besides doing hard things that level you up, you can get big gains by doing many things and switching as soon as you get bored (which is hopefully calibrated to how challenged you are).

You may remember early in the Arabian revolutions in Libya, an American student took the summer off college to fight in the revolution. I bet he learned a lot. If you could do enough things like that, you'd be well on your way to matching the vampire.

This actually goes hand in hand with doing hard things; when you're not feeling challenged (you're on the flat part of that experience curve), its probably best to throw yourself face first into some new project, both because it's new, and because it's hard.

Switching often has the additional benefit of normalizing strategic changes and practicing "what should I be doing"-type thoughts, which can't hurt if you intend to actually do useful stuff with your life.

There are probably many cases where full on switching is not best. For example, you don't become an expert in X by switching out of X as soon as you know the basics. It might be that you want to switch often on side-things but go deep on X. Alternatively, you probably want to do some kind of switch every now and then in X, maybe look at things from a different perspective, tackle a different problem, or something like that. This is the Deliberate Practice theory of expertise.

So don't forget the shape of that experience curve. As soon as you start to feel that leveling off, find a way to make it fresh again.

Do Things Quickly

Another big angle on this idea is that every hour is an opportunity, and you want to make the best of them. This seems totally obvious but I definitely "get it" a lot more having thought about it in terms of becoming a 1000 year old vampire.

A big example is procrastination. I have a lot of things that have been hanging around on my todo list for a long time, basically oppressing me by their presence. I can't relax and look to new things to do while there's still that one stupid thing on my todo list. The key insight is that if you process the stuff on your todo list now instead of slacking now and doing it later, you get it out of the way and then you can do something else later, and thereby become a 1000 year old vampire faster.

So a friend and I have internalized this a bit more and started really noticing those opportunity costs, and actually started knocking things off faster. I'm sure there's more where that came from; we are nowhere near optimal in Doing It Now, so it's probably good to meditate on this more.

As a concrete example, I'm writing tonight because I realized that I need to just get all my writing ideas out of the way to make room for more awesomeness.

The flipside of this idea is that a lot of things are complete wastes of time, in the sense that they just burn up lifespan and don't get you anything, or even weaken you.

Bad habits like reading crap on the Internet, watching TV, watching porn, playing video games, sleeping in, and so on are obvious losses. It's really hard to internalize that, but this 1000-year-old-vampire concept has been helpful for me by making the magnitude of the cost more salient. Do you want to wake up when you're 30 and realize you wasted your youth on meaningless crap, or do you want to get off your ass and write that thing you've been meaning to right now, and be a fscking vampire in 10 years?

It's not just bad habits, though; a lot of it is your broader position in life that wastes time or doesn't. For example, repetitive wage work that doesn't challenge you is really just trading a huge chunk of your life for not even much money. Obviously sometimes you have to, but you have to realize that trading away half your life is a pretty raw deal that is to be avoided. You don't even really get anything for commuting and housework. Maybe I really should quit my job soon...

I have 168 hours a week, of which only 110 are feasible to use (sleep), and by the time we include all the chores, wage-work, bad habits, and procrastination, I probably only live 30 hours a week. That's bullshit; three quarters of my life pissed away. I could live four times as much if I could cut out that stuff.

So this is just the concept of time opportunity costs dressed up to be more salient. Basic economics concepts seem really quite valuable in this way.

Do it now so you can do something else later. Avoid crap work.

Social Environment and Stimulation

I notice that I'm most alive and do my best intellectual work when talking to other people who are smart and interested in having deep technical conversations. Other things like certain patterns of time pressure create this effect where I work many times harder and more effectively than otherwise. A great example is technical exams; I can blast out answers to hundreds of technical questions at quite a rate.

It seems like a good idea to induce this state where you are more alive (is it the "flow" state?) if you want to live more life. It also seems totally possible to do so more often by hanging out with the right people and exposing yourself to the right working conditions and whatnot.

One thing that will come up is that it's quite draining, in that I sometimes feel exhausted and can't get much done after a day of more intense work. Is this a real thing? Probably. Still, I'm nowhere near the limit even given the need to rest, in general.

I ought to do some research to learn more about this. If it's connected to "flow", there's been a lot of research, AFAIK.

I also ought to just hurry up and move to California where there is a proper intellectual community that will stimulate me much better than the meager group of brains I could scrape together in Vancouver.

The other benefit of a good intellectual community is that they can incentivize doing cooler things. When all your friends are starting companies or otherwise doing great work, sitting around on the couch feels like a really bad idea.

So if we want to live more life, finding more ways to enter that stimulated flow state seems like a prudent thing to do, whether that means just making way for it in your work habits, putting yourself in more challenging social and intellectual environments, or whatever.

Adding It Up

So how fast can we go overall if we do all of this?

By seeking many new experiences to keep learning, I think we can plausibly get 10x speedup over what you might do by default. Obviously this can be more or less, based on circumstances and things I'm not thinking of.

On top of that, it seems like I could do 4x as much by maintaining a habit of doing it now and avoiding crap work. How to do this, I don't know, but it's possible.

I don't know how to estimate the actual gains from a stimulating environment. It seems like it could be really really high, or just another incremental gain in efficiency, depending how it goes down. Let's say that on top of the other things, we can realistically push ourselves 2x or 3x harder by social and environmental effects.

Doing hard things seems huge, but also quite related to the doing new things angle that we already accounted for. So explicitly remembering to do hard things on top of that? Maybe 5x? This again will vary a lot based on what opportunities you are able to find, and unknown factors, but 5x seems safe enough given mortal levels of ingenuity and willpower.

So all together, someone who:

  • Often thinks about where they are on the experience curve for everything they do, and takes action on that when appropriate,

  • Maintains a habit of doing stuff now and visualizing those opportunity costs,

  • Puts themselves in a stimulating environment like the bay area intellectual community and surrounds themselves with stimulating people and events,

  • Seeks out the hardest character-building experiences like getting tear gassed in a trench or building a company from scratch,

Can plausibly get 500x speedup and live 1000 normal years in 2. That seems pretty wild, but none of these things are particularly out there, and people like Elon Musk or Eliezer Yudkowsky do seem to do around that magnitude more than the average joe.

Perhaps they don't multiply quite that conveniently, or there's some other gotcha, but the target seems reachable, and these things will help. On the other hand, they almost certainly self-reinforce; a 1000 year old vampire would have mastered the art of living life life at ever higher efficiencies.

This does seem to be congruent with all this stuff being power-law distributed, which of course makes it difficult to summarize by a single number like 500.

The final question of course is what real speedup we can expect you or I to gain from writing or reading this. Getting more than 2 or 3 times by having a low-level insight or reading a blog post seems stretching of the imagination, never mind 500 times. But still, power laws happen. There's probably massive payoff to taking this idea seriously.

An interesting post. Two directions for more thinking:

(1) Goals. What do you want to get out of this? What do you really want? Doing lots of things quickly and intensely is one way to describe a rat race. Yes, you can run faster but where are you running to?

(2) Risks. There is a certain aura of invincibility surrounding this post. But do remember that shit happens and vampires happen to be already dead and quite hard to kill (again). You have to make sure that your broad intense experiences aren't putting you into running for the Darwin Award. That American student who fought in Libya -- what were his chances of coming home in a body bag? or coming back with severe PTSD and becoming emotionally disabled?

Goals. What do you want to get out of this? What do you really want? Doing lots of things quickly and intensely is one way to describe a rat race. Yes, you can run faster but where are you running to?

Good question. This thing has a lot of opportunity for lost purposes. My particular goal is get enough power to save the world, which does sometimes disagree with maximum vampire-mode. They often agree though, and the vampire heuristic pushes harder than the save-the-world goal, because vanity metrics like "how vampire-mode are you" are more motivating than important things like saving the world.

Risks. There is a certain aura of invincibility surrounding this post.

Another good point. Let's not be stupid and get killed. I for one would think that it is probably not a good idea to go fight in a revolution or other dangerous activities, but I put it in anyway because it was a good example.

My particular goal is get enough power to save the world, which does sometimes disagree with maximum vampire-mode.

Maybe instead of thinking in 1000-year-old vampire terms for this, it's better to think in intelligence explosion terms. For example, let's say you have a list of goals you want to accomplish. One is get more sleep, which you expect, among other things, to improve your focus. Another is meditate intensely for 10 minutes every day, which you expect, among other things, to improve your willpower. Each of these goals helps to some degree with the other. If you had a lot of goals that all improved your capacity to work towards the other goals, and improved your capacity in general, then you could potentially see exponential growth in your ability to do things. (Some of your goals should probably be object-level though, because it's good to intermix self-improvement goals with object-level goals to see if you are actually building the kind of capacities you need.)

But lets say that you've tried and failed at both the meditation and sleep goals in the past. In that case, you are having a hard time getting the exponential growth cycle started, and you're probably better off taking things from another angle, kind of like a game of sudoku. So develop and test a hypothesis about why your meditation goal failed, or read up on strategies people have to overcome whatever problem you think you were having. Or alternatively, try to find the small capacity-building thing that you think is quite likely to stick for the long term, and try to achieve it so you can gain a toehold. Then celebrate and attempt the capacity-building thing that you think is the next hardest to get to stick, etc. This also doubles as establishing a success spiral and builds the ability to maintain commitments to yourself (and is also kaizen).

Probably the easiest sort of "toehold" to establish is just to start learning more about yourself. Read up on ugh fields, reinforcement, and stuff like it. Maybe spill your guts to a friend, or start keeping a productivity diary... every entry you make has a small expected self-knowledge gain. Basically try to get as much insight as you can in to yourself, because self-knowledge is an irreversible capacity gain (unlike, say, a habit, which, once lost, will have to be re-established).

(I'm sure I'm not the only one who's wondered if the effective altruist community is best off overtly telling everyone we are focused on things like Givewell, MIRI, etc. but covertly choosing to focus most of our resources on capacity-building, knowing that the goals we've set for ourselves are big enough that they aren't going to be realistically accomplished with our current cohort.)

Back when I was trying to quit cigarettes I had many different types of motivation to get me to stick with not smoking. Money, health, and dating were all reasons for me to quit, and they didn't work until I found a way of thinking about it that just clicked for me – I didn't want to be 'that guy', that low status loser who couldn't stop smoking, someone that just didn't have it in him to quit. So I quit.

I really liked this post because much like when I was trying to quit cigarettes, it's giving me a different way of thinking about my procrastination that might really click with me. This is a new insight; I want to get things done now and faster, so that I can make room for being fucking awesome!

Fuck yeah! Let's get off our asses and become 1000 year old vampires.

Glad to know it clicks for you.

This article makes some great point, however I think you are other optimizing. Specifically, these seem more like techniques for Unlocking Massive Latent Potential (that most people don't have), or curing lazy/spoiled but already awesome people. That's very much worth writing an article over, since those are probably where most potential rationalists will come from, but it's not the same as an universal formula for awesomeness.

That wouldn't be a problem - social/environmental stimulation and diversity of experience are good for you even if it doesn't turn you into a badass. However, many of the techniques are dangerous if tried by a median human; getting rid of de-stressing activities and entertainment or taking on more responsibilities or than you can handle can burn you out, doing hard things and overloading yourself risks downright trauma and injury, and other hard things or quitting your job could leave someone in permanent financial ruin and unemployment.

What I suspect has happened here is the same type of selection effect as in books on how to get rich by extremely rich people - just because almost all members of desirable group X did Y, doesn't mean doing Y is a good idea; you never heard of all the many more people that did Y and failed ending up in a much worse position than if they had just stuck with status quo. Being member of an elite doesn't just select for strategy it also selects heavily for talent and luck, and different strategies may be optimal depending on the amount of talent and luck you have.

Ha, it is not until very recently that people have accused me of Latent Destiny.

I've been thinking about this, and I think that most people who have Latent Destiny do not believe that they do, and never achieve greatness because of that. People like that need to know that it's possible, and need some inspiration like OP.

As for everyone else, humans are pretty robust and will at least exercise basic judgement before doing stupid life-wrecking things based on a bad reading of an internet article written by someone called Nyan Sandwich. And if they don't exercise such judgement, someone else's dangerous advice would get them if mine did not.

But that's beside the point, because a few medians (perfect word for them, thank you) is an easy price to pay for another hero. If dangerous advice is necessary to create heroes, such dangerous advice is good, because we need more heroes, and we are at a point in history where the instrumental value of people dominates the intrinsic.

The selection effect comment is interesting, probably some truth. I'll think about that.

You are almost certainly right about this not working for everyone. Still, applied well it could produce gains in most.

we are at a point in history where the instrumental value of people dominates the intrinsic.

On your view, has this ever been false? If we can justify treating people as means rather than ends now, I can't imagine a time when we couldn't justify it.

Yes, in the grand scheme of things, the overwhelming value of historically existing humans is in enabling our glorious future, and this has always been true so far.

(Not to understate the awesomeness produced so far, just that so much more is possible)

At least, that's, like, my opinion, man.

OK, cool.

And sure, I was just making sure I understood your position; your emphasis on the point we are in history left me uncertain whether there was some other point where it wasn't true.

I now feel compelled to add that to the extent that I expect you to act accordingly I will avoid you having power over anyone I care about, as I distrust the willingness to sacrifice existing people in order to enable a vision of our glorious future. That sort of thing has an iffy hit rate with humans; we tend to be overconfident about our specific details of our visions of glorious futures.

Bad habits like reading crap on the Internet, watching TV, watching porn, playing video games, sleeping in, and so on are obvious losses.

Objection: I like all of these things. Well, except watching TV. Calvin said it best: "There's never enough time to do all the nothing you want."

But I actually like the goal of becoming (the equivalent of) a thousand-year-old vampire, too. And there's not enough time for that, either. That is, ultimately, what convinced me that death is bad and life extension is good: There's not enough time to do life right. Doing it right, at least for me, means both becoming awesome and sleeping in when I feel like it.

It's not just bad habits, though; a lot of it is your broader position in life that wastes time or doesn't. For example, repetitive wage work that doesn't challenge you is really just trading a huge chunk of your life for not even much money. Obviously sometimes you have to, but you have to realize that trading away half your life is a pretty raw deal that is to be avoided. You don't even really get anything for commuting and housework. Maybe I really should quit my job soon...

If your field of expertise pays, you can level up while still getting paid by changing jobs regularly. I am not sure how often "regularly" should be, but I noticed a huge boost in my own skills the last couple times I started a new job in my field, followed by eventually getting bored and leveling off. Assuming you're following a normal career, you can't change too often or getting the next job will become hard; but if you're bored, complacent, and inert, it's probably time to move on.

[Edit: is Noticing Boredom a recognized mental skill? Because it should be.]

Full disclosure: I'm in the process of trying to do exactly this now. Note to six-month future self: Reflect on whether I actually did experience a similar skills boost after switching.

I have 168 hours a week, of which only 110 are feasible to use (sleep), and by the time we include all the chores, wage-work, bad habits, and procrastination, I probably only live 30 hours a week. That's bullshit; three quarters of my life pissed away. I could live four times as much if I could cut out that stuff.

Amen.

Also, on the topic of social environment, here is the obligatory plug for the Less Wrong Study Hall. If you're outside the Bay Area and have no one to work with, come work with us. We have cookies. (cookies may be a lie)

is Noticing Boredom a recognized mental skill? Because it should be

Very much agreed. When I started taking online courses I was surprised at how speeding up the video helped my learning. What was happening before, and what still happens when I'm watching slow, informationally dilute speeches, is my mind can't sync up with the presentation and it wanders off on its own way so frequently that I simply can't stop it from happening. I also didn't used to realize how hanging around with crowds who wern't curious and wern't agenty in the same way I was sucked the life out of me. I thought I was just an inattentive, generally disengaged person. I was dead wrong.

Objection: I like all of these things.

Good point. I like all of these things as well, except that I have no time for hedonism. So much to do! So little time! As you observe.

So if you are basically a Sensate, seeking to experience everything in the multiverse, then (good) Internet articles, books, TV and video games are like memory stones: objects containing the experiences of others, which allow you to experience something that you might never be able to experience yourself.

It's a trade-off. Media provides alternate experiences much faster than you could do them yourself, but also at a more shallow level. There's a case to be made for alternating between both: once you have viscerally experienced something yourself, reading about something related may make for a stronger experience, since it activates more memories and associations in you and allows you to better simulate the original experience behind the account. At the same time, having experienced second-hands accounts of something may make things in real life more rewarding to experience, because you can look at them from points of view that wouldn't have occurred to you if you were only going on your own experience. Some of this may come via very unexpected routes, such as the time when I ended up playing sports and ended up appreciating them more due to my gaming experience:

Ended up playing some sähly (rather like floorball, with some differences such as a lack of goalies) yesterday, and was somewhat blown away. My previous experience with sähly, football, etc. had come from the physical ed lessons in school, and I'd mostly experienced it as aimless running around the ball.

But this time around, I'd played enough strategy games to pick up on the fact that the game actually had a definite tactical dimension as well. Now I didn't realize anything terribly complicated, mostly just basic stuff like "well I could be rushing on the offense, but then if the ball gets thrown back to our side of the field, then everyone in our team will be on the wrong side, so maybe I should hang back a bit" and "I should go after that guy with the ball, even though I won't get it from him I can force him to pass it to someone else, which is much better than letting him do whatever he wants". But I'm not sure how much I ever thought in terms of those kinds of concepts back in elementary school - e.g. I'm pretty sure that I only had the latter insight now because I'd played enough strategy games and had read articles about military strategy.

I imagine that if our PE teachers had bothered actually explaining to us that these games had an intellectual component as well, and weren't just about pure physical fitness, geeks like me would've enjoyed the thing a lot more.

I like this post, and I feel it is a great demonstration of how optimality as a motivator basically sucks without an emotionally engaging picture/narrative to tie it to. For the longest time I failed to get that the ancient marketing wisdom of "tell a story people want to be a part of" works just as well on yourself as others.

Totally. It's important to beat these ideas into a shape consumable by a human. I've been thinking about doing this with "Epistemology for Humans". Perhaps I will.

I disagree with several of your points, but I upvoted this post anyway because I think this is the type of thing that we should be discussing more on LessWrong. I'll have a more substantive reply tomorrow.

You may remember early in the Arabian revolutions in Libya, an American student took the summer off college to fight in the revolution. I bet he learned a lot.

Probably, but how much of that was actually useful for, say, making more money? And did he learn more than he would have if he'd spend the summer reading random interesting stuff on the internet? (Much lower status, but not obviously less educational.)

BTW, as far as I can tell Eliezer spent several years of his life doing fairly slow work on a rationality book as his primary project, and this book never ended up getting published. So I'm not sure he should be held up as an example of someone who gets a lot done. (And this seems to be what he himself has indicated in his writings on procrastination.) Beware the halo effect.

(I liked this post but wanted to play devil's advocate.)

Is there a better term for this than anything usually associated with a cold and ruthless blood-sucking nocturnal killer?

As I mentioned earlier, I like this post, but a lot of the suggestions seem very hazardous. For instance, you write that "You may remember early in the Arabian revolutions in Libya, an American student took the summer off college to fight in the revolution. I bet he learned a lot. If you could do enough things like that, you'd be well on your way to matching the vampire."

It doesn't strike me that this is even a remotely good idea for personal development reasons, and I'm not even talking about the risk of death.

If you want to optimize your life for adventure, that's fine-- I once knew someone who held that the only things anyone actually optimized their life for were money, love, and adventure, and everything else was fake. But it doesn't seem to me that this is necessarily good for learning.

People often say that I have had an unusually wide range of experiences, and in many respects that is true. However, it isn't clear to me that this is a strategy that people should intentionally play. I know several people who have essentially optimized their lives for having crazy experiences, and to me this seems much more questionable than one might expect. Eventually-- and often quite rapidly-- "having crazy experiences" itself becomes a thing that these individuals are doing too much.

Much like being cool, classy, or honest, trying to be interesting or do interesting things often does not make you interesting-- indeed it can make you the reverse. I think a perhaps better tactic is to find the interestingness in otherwise mundane activities. In my experience this can yield similar benefits to intentionally trying to go out and do interesting things, but has much lower costs.

After reading this, I stuck a note saying "Be a vampire" to the front of my computer (which is my main source of procrastination).

Also, this post reminds me of the fact that being a hard sciences student is one of the things which helps me keep 'leveling up' on a regular basis, which is strong motivation to get me to do my coursework.

...I keep forgetting that for normal people, sleeping in is actually lazy, and not a survival tactic to recover from the sleep deprivation of doing 12 hour rotating day-night shifts in time to do more shifts.

I've had this attitude of "do hard things" for a while, although the hard things I've done (mainly jumping into critical care nursing as a new grad) aren't super typical for LW. I guess technically I work a wage job, but it's also incredibly meaningful work that pushes me to my limits every single day and is gradually transforming me into the kind of person I want to be; y'know, calm under pressure, smiling in the face of adversity, organized, good at teamwork, good at empathy and reading people's emotions, etc.

I've considered joining the army for a similar reason of pushing myself to become stronger. Unsure if I will still do this, as moving to the Bay Area is probably higher value.

I've considered joining the army for a similar reason of pushing myself to become stronger.

For me, the military did not push me nearly as hard as I expected. Pushed myself harder while preparing for it than I was pushed in Basic Training. Advise not doing this, or at least joining Marine Corps instead for proper pushing. There are also things (i.e. Tough Mudder) that can similarly physically push you without requiring you to sign a contract.

This is a good point; there are almost certainly ways to get the important parts of the military experience without paying the costs.

I'm not sure that the example of your friend who joined the Army and then became a millionaire means much: most people who joined the Army did not become millionaires; most millionaires were never in the Army.
