A case can certainly be made that golf is definitely the most frustrating game that has ever been invented.  I do not care who you are, if you take the game even a little bit seriously, then will be times that frustration takes over from all lucid thoughts. 

Anger is most definitely the enemy; you lose focus and once your concentration dips the end is nigh.  Anger is the counterbalance of confidence and in golf if you lose that confidence every shot seems so much harder. 

Emotional content and intensity cannot be allowed to take control of your body whilst playing golf, it is totally counterproductive, it will colour everything that you are trying to achieve. All the positive thoughts you took with you onto the golf course will so be lost to the red mist.

So how you adapt and learn to control that anger? 

There proven anger management techniques, but these require the individual to focus elsewhere.  In golf we need to address the same situation in a different manner, we need to address the problem before it actually occurs.  In a manner of speaking you condition yourself so that instead of feeling the anger that comes naturally now, you will experience something akin to a learning experience. This allows you to move on and consider how to improve rather than what went wrong.

Controlling your emotions is not as complex as it might sound; it is simply a matter of allowing yourself to understand why this anger has been released.   Most of the time the anger will initially be targeted against yourself, after all the shot you played was your responsibility.    But of course human nature kicks in and you want someone else to blame.  So before you launch poor Bob done the fairway for daring to say hard luck, take a few breathes and try some relative thinking.   You may think this is farfetched but there is documented evidence of assaults, serious injury and even jail time derived from incidents on the golf course.

Anger will achieve nothing, it will make things worse.  We all know this, now we need to act on it.

Conditioning the mind to react in a certain way when dealing with anger issues cannot be pigeon holed to just golf.  This means that you have to face this in everyday life as well.  You cannot condition yourself to act in a certain way only part of the time, nor should you want to.

Try to remember the last occasion you let you anger dictate your game; remember how long this feeling lasted and the ramifications.  Picture then how you would like to have done this differently.  Put the scenario into your mind, removing the negative and replacing with the positive.  You need to train you brain so this becomes natural, the more you do this the more the mind will relate anger to solution.   As you progress you will find that the instant the anger tries to flare up you will be thinking of how to put it right.  Yes this will not eradicate the mistakes, you are only human after all, but it will mean that one bad stroke remains one bad stroke, not a bad hole, and never a bad round. 

Now don’t worry you are not going to end up like an extra in a Walt Disney cartoon being serenaded by a host of cartoon animals. You are just going to learn to relax and see that anger is not in any way beneficial to producing results.
