 We all know we're going to make mistakes, but we cannot be in the business of compounding them. Don't worry about the play that just happened. Ed, you just missed the layup. Don't worry about it. Next play. Ed, you just turned the ball over. It's okay. Next play. Ed, I know the referee missed the call. It's over. Next play. If you're still pouting and dejected about the turnover, your man probably just scored two points now on the other end, so you just turned a two-point mistake into a four-point mistake.
