If you are angry on the golf course it can cause problems and ruin the enjoyment of the game. Anger changes your whole game and you rush your shots, and you rush your swing, heck you even rush when you walk. Sometimes POP (pissed off Power) with your new Nike golf clubs, you know, the big square one, will get you a long straight tee shot. But usually it will get you a short worm burner or worse yet, out of bounds. Calming down is essentual to your next shot. That is not how to drive a golf ball consistently where you want it to go.
If you walk slower and think calm down you will be better for it. When you reach your golf ball take your time on the shot. Take a long look at all the options and slowly pull out the golf club. Then take extra practice swings and a couple of deep breathes. Get your positive focus going and make the best stoke of the day. Now you are back on track.
Pay attention to what you tell yourself after a bad shot, negativity feeds off of it self. Eliminate the negative to yourself, yes it was a bad shot and it is ok to say that but then move on with, you are better than that, the next golf shot or putt will be better than that one. Be your own coach and talk positive, after all it is just golf, enjoy the game.
