Socrates. Nietzche...although, I agree he is hard to understand.

A certain homeless guy at my nearest train station. He's always there trying to pinpont the single moment where his life went wrong. If you actually talk to him long enough (I tend to get chatty when I am intoxicated), he's not as crazy as you'd think he'd be. Kinda scary, cause I've definitely been in related situations or made similar choices.

Carl Sagan is the shiz.
