We teach people that mistakes are like skinned knees for little children. They're painful, but they heal quickly and they're learning experiences. My people are covered with the scars of their mistakes. They lived out in the field, the've been shot at; they've been hit in every part of their bodies; and they're real. By the time they get to the top, their noses are pretty well broken. The chances of their getting there with a clean nose is zero.
