I consider myself athletic type. Play team sports like soccer, basketball, swim, individual sports badminton, running, table tennis and etc. I never got frustrated in any sports but tennis. You don't see, table tennis players throw the paddle or squeeze the ball or badminton player pick out all the feathers from the shuttlecock or break the racquet. Basketball or soccer players shout or talk to the ball when thing don't go their way. Why Tennis, please tell me what is so wrong with this sport. I watched Federer throw his racquet at Nasdaq 100 yesterday. A cool guy like him, show how frustrated the game is. I guess losing the cool, most of the time help me play better and improved my mistake. But keep whinning and shouting on my mistake, kind like embarassing too while many people watching. I can't help myself.
