Once you've played a good shot, remember it. Remember how it felt. Remember how relaxed you were and how clear your mind was. Remember how smooth and natural the swing was. See yourself playing that shot in your minds eye just like a photograph. Imagine your mind as being like a computer with different files. File that memory under 'Golf Successes' Oh, and well you're at it, empty the contents of the 'golfing failures and disastrous shots' folders into the trash can.
