Missing a high percentage shot causes any player anguish. How we react sometimes affects not only the match, but teammates, upcoming matches, and perceptions of your demeanor. Those of us with a Type A personality traits undoubtedly have more difficulty remaining calm. I, admittedly, become agitated to a fault at times. I am able to reign in my attitude afterwards, but fully realize the discomfort I have caused others. Truthfully it's not about winning and losing so much as it is performance in the moment. I'm trying to learn how to keep the proper perspectives of competition and sincerely want to give my opponents and the sport the respect they deserve. May I ask, what techniques or thoughts others use to deal with their mistakes calmly ?
