ometimes amateurs believe they are professionals, but professionals never believe they are amateurs. Professionals know they are not playing the same game as amateurs.

t is remarkable how much long-term advantage people like us have gotten by trying to be consistently not stupid, instead of trying to be very intelligent.

The point is that most of us are amateurs but we refuse to believe it.

This is a problem because we’re often playing the game of the professionals. What we should do in this case, when we’re the amateur, is to invert the problem. Rather than trying to win, we should avoid losing.
