I'm very competitive and I let my emotions show. Most of the time what you see is me being upset with myself. I expect to be almost perfect, but I'm human. So, when I'm not perfect, I really get mad at myself. I always expect more of myself than I do of anyone else, and when I'm not delivering, there's nothing that makes me more upset.
The scoreboard can't make you a loser. If you walk off the field with your head up, you don't lose. You don't hang your head for nobody. People in the stands think you're the greatest or the worst - their opinion doesn't make a difference. The only opinion that makes any difference is your own opinion of yourself. Nobody can make you a loser.
