The crux is the realization of the absurdity of (unrealistic) expectations. Those who figure it out early are able to find balance. But those who succumb to it generally end up hating themselves and their research because of how inadequate it makes them feel.

I do agree upon the role Bethe played in Feynman's early career and I think both of us concur that we need more Bethes today.
