People like Elon Musk for example had lots of problems as a kid, he was bullied a lot.
Steve Jobs also had a lot of problems and as a person he was very difficult to manage.
Steve Blank had lots of problems in his childhood too.
I personally know well one of the richest persons in the planet, because of a common hobby. I am not that rich, I don't envy this person and what he went through.Life becomes so easy after that, even in hard times.
It is fairly common, it looks like if you survive such strong experiences it can benefit or punish the rest of your life. Some will go to the streets , others will rule companies.
In particular, I believe it has a lot to do with your attitudes toward risk. And of course luck, but most of these people can help but keep trying.
If you try 10 times and fail most people just leave. But if you continue and success in the 12th, it is no luck. In fact if you never succeed your behavior will be called and obsessive compulsive and pathologic.
How many times Elon Musk tried to launch and then land a rocket?, the personal risk that he took was astronomical, most normal people will leave soon under the same circumstances.
I have seen people doing that, succeeding only at the end, for example when normal people did it in search for gold it was called the "gold fever", because people kept trying and trying, even with failure after failure.
Of course when you succeed everybody knew you were the man(the same people that criticized you when you failed), everybody wants to be your friend, and politicians want the money you have(and want to raise your taxes with excuses like how lucky you are or not being fair).
