Am I the only one that gets suicidally depressed when he isn't solving the great problems of science? Actually, I can stave off suicide if I feel that I am actually learning something. I don't have to actually solve any great riddle. I'm too lazy to look it up, but Feynman talked about this, there's a youtube video on it. He said that there's a great pain, when you don't understand something. It hurts you, bad. I think that's what drives me, though. Does anybody else feel this burden to understand things? Something that actually hurts? Or is this all a game to y'all?
