Warren Buffett: When others are greedy, I’m afraid, when other are afraid, I’m greedy.
I'm reminded of the torture scene in the Serpent and the Rainbow where the torturer tells his victim "I want to hear you scream," and the victim screams loudly in terror, and the torturer replies "not loud enough" and begins to do unprintable things.
Yes, when others are afraid I'm greedy. But they're not nearly afraid enough yet.
