I can't stand people who say 'I told you so.' That's worse than somebody coming up and eating your dinner before you have a chance to sit down.

Fantasy is, I believe, the great nourisher of imagination. To paraphrase Einstein on how to develop intelligence in young people: Read fairy tales. Then read more fairy tales.

For man to be worthy of any rank, he must strive first to be a man.
