1. Stay in the moment. Try the one shot at a time approach, and don't tilt because of a bad shot on the previous hole(s).
2. Maintain the intensity. Try to match my back 9 score to my front 9 score. This means avoiding the inevitable fatigue that causes my swing to fall apart.
3. Work on lag putts. Don't get complacent with the lag putts. Make sure to work hard on them and get them within 3 feet of the hole (minimum).
