And you will have been part of it and be able to say "I did something great and it changed the world".
But most of us won't be people who are remembered and written about, like Satoshi, Craig Wright, etc.
Nor do I think we need to be, and as far as doing something remarkable with our lives, I like to think that I do small but remarkable things at my job that, if they don't exactly change millions of people's lives, at least help people on an individual level. The way I see it, I could be doing much worse with my lot in life, and I was never looking for fame and fortune anyway so I'm not disappointed.
Paxmao, you're correct that people like you mentioned are rare. You can aspire to be a Nobel Prize winner and there's nothing wrong with that, but if you set your expectations that high you're bound to be a more frustrated and angry person as time goes on. Notice I didn't say that one shouldn't work toward such a goal, just that your
expectations should be much lower (if you want to be happy, at least).
