Why do men outperform women on the SAT? The SAT's supposed to predict college grades. Women do better in high school and they do better in college. What's the problem here? Ah, the more you use, the more you start accepting that the SAT's coachable, the more problems you have with it.

The question was, in a sense, at Princeton Review, how much value was I adding as a public company CEO. I was adding less than other people might've... I think you want to move on when you've given your best work and then feel that you're not going to add as much value moving forward.
