"I've seen men who thought they were brave turn out to be shameful cowards. Other people, who thought they were capable of the utmost self-sacrifice, proved to be hardened egotists. And the opposite, too - cowards doing things which needed toughness and unusual courage..... What does it all boil down to in the end? One must judge a man by what he does, and not by what he thinks he would do. Until a man faces the test, he can deceive himself endlessly."
