The Three Virtues of Hungry

A person who is only smart. They're really a genius in working with others, but they're just not humble and they're not hungry. Not of the guy you want in a group project at school or at work. It might be fun to party with, but probably not the guy you wanted on your team. A bulldozer: somebody who just is going to get it done no matter what. But bulldozers usually don't do too well in life either.
