Great quote from David Einhorn in the Charlie Rose interview linked to in the previous post:
CHARLIE ROSE: What is it you like about what you do, because you didn’t set out to do this?
DAVID EINHORN: No. What I like is solving the puzzles. I think that what you are dealing with here is incomplete information. You’ve got little bits of things. You have facts. You have analysis. You have numbers. You have people’s motivations.
And you try to put this together into a puzzle -- or decode the puzzle in a way that allows you to have a way better than average opportunity to do well if you solve on the puzzle correctly, and that’s the best part of the business.
