The drive to achieve that level of success often comes from weaponized poor self esteem.
Well adjusted individuals just chill out after a few million and work on whatever is fun/important for them.
Only rarely does this also happen to be something that can take you from 10M to 1B. (and if it can it would take a lot of work you can't be bothered to do unless it's some core value like helping the poor beat malaria)
