Same can be said about children from good backgrounds. What makes Donald Trump's kids 'successful'? I know some extremely privileged people in the early 20s that could do anything, are very attractive, have no worries but live a life of complete chaos. I know others who were smart and super wealthy, but stumbled and couldn't recover emotionally/mentally.

I personally think it has a lot to do with stoicism and those who look for solutions vs those who just try to cope.
