Sometimes the simple act of dressing is all you need to motivate you. Use your imagination. Before your weekend four-ball, pretend you're Tiger Woods or some other PGA Tour star. You just might surprise yourself. Put on your game face.
Peak performance requires optimal arousal and motivation, but avoid turning into a bundle of nerves.
Identify your physical reactions and learn to control them. To minimise muscle tightening and jaw clenching, practice deep breathing or progressive muscle relaxation. The more you ritualise these techniques in practice, the more likely they are to help you keep your cool in game situations. Warm up your muscles and your mind. Develop rituals for the warm-up portion of your workout.
