Another poster had an interesting observation about academia vs corporate work. I'm 33 and still in academia, and I now realize a large part of that is the freedom it provides. I've see salary as a score on someone else's scoreboard, and very uninteresting for that reason. OK, I'm old enough to have experienced a person needs income for practical reasons, but I'm not going to work for it ;)
I'm allergic to competition, scores, rewards, prestige, I guess that makes me child-like?
