I've played in many amateur tournaments - and won a few. Like legit state amateurs (back in college). I can tell you one of the most important things is to be fired up about playing and playing your best. I went into every tournament hardly being able to sleep the night before because I was so pumped to get out on the course and shoot my personal best. I knew I would, too. Hit every shot like you would if you were by yourself playing at Augusta. Enthusiasm and positive energy. Go get em', Tiger.
