It is definitely worth repeating that you should never attempt to change your golf swing whilst you are on the course. You can do this on the range or with the pro. The course is the place where you enjoy playing the game. Of course, your routine will include weighing up distances, conditions etc but once you are ready to take that swing you must empty your mind of all but a superhuman certainty of where your ball is going to go. This beautiful moment of internal harmony and confidence is when the naughty golfer is likely to make his of her appearance. Just be aware of this, and prepared to pause, clear your mind once again. Look at the target, look at the ball and take the shot.
