Oh, this is an easy one. When people say a child is talented they mean he or she is a good learner. But a talented adult is a good do-er. High potential people who fail to make an impact are stuck in child-mode, because that is what they were always praised for.

indeed, by success people usually mean make lots of money, is this the definition of success to a High IQ person? maybe, but perhaps it means why can't I solve Fermats last theorem or something they think is important.
Or put it this way - smart people will only solve the problems smart people see as problems.

Or I would say 'as interesting' and we know it can be hard to find intersections of interesting and well paying.
The habit I formed was enjoying using creative connections. Unfortunately there's lots of reasonably well paying posts for repeating yourself and it's easy to be complacent in your career and have hobbies instead.
