if you ever play alone, DO you get mad? Because whether you believe it ornot, no one cares if you hit a bad or good shot, obviouisly most people want you to play well, but if you dont itts not the end of the world. You arent judged by the scores you make on the course, however you will be judged by your temperment, you probably dont make golf very enjoyable forthe people you play with. Also, you may need to ask yourself if you really enjoy golf, or if you just enjoy shooting low, because if its the latter then maybe you shouldnt play because you really dont enjoy it. How well you score is not indicitive of your personal worth. You need to just realize getting angry is juvenile and it shows lack of self esteem (or that you are psycho) Trying to "control it" doesnt help the problem, realizing what the problem is and then figuring out how to get rid of it does. Having a bad "temper" is a horrible excuse for everyone to have, if you are an adult get over yourself (sorry if this come soff harsh, I used to have a problem with getting angry and realized that I never got angry until I started playing with a friend of mine who used to go berserk on the course, I started playing with much older better players and assessed why I got angry and now I enjoy golf as much as I ever have, dont worry about your score and take things as they come, it all evens out in the end anyway)
Also, just remember you are paying to play, if you get psised off and dont enjoy playing dont play, and no one gives a damn about your score but yourself, so dont tell everybody about it because it gets old.
