* Plan your strategy for the game, days before the game, if not weeks. (e.g. a birdie for every hole - strategy)
* remember tunnel vision for your focus; go into focus just before you play, i.e. when you are hitting the ball nothing else maters, just you hitting the ball to your chosen destination, once done relax your focus.
* to help you go into the focus mode; say quietly in your mind what your are going to do, over and over again about 4 or 5 times to convince your subconscious mind so that your subconscious and conscious minds are both in sync.
* Most of all be confident and have belief in yourself, you can do it, go ahead and win it
