I always tell students that the only time you lose is when you don't give 100% effort. In competition, only one can win. You go to a tournament and hope that you will win. No matter what you have to think like a winner and do all that you can to do so. If you've trained hard and put your heart and soul into it, then you can keep your head up in defeat. I don't see that sometimes. If you get upset and make excuses then you are a loser.
