Many people say that wealth is a reward for cognition.
But I feel that a person's substance and his/her wealth do not seem to have a necessary relationship.
I know some extremely wise people who live extremely simple and impoverished lives. They really seem to not care much about money.
I have also seen many people who earned millions or tens of millions by themselves,
but I have really not seen anyone who earned over a hundred million by themselves, no, not a single one.
Is there some secret in between this?
