I don't have a similarly stylish and philosophical story as coffeemug's but the thing that changed the way I perceive criticism is something I've read a while back: before coming up with any answers or remarks, ask 3 questions about the original thing. Agreed these 3 questions shouldn't be: 1) WTF? 2) who is he to criticize? 3) should I bother?)
