He has achieved his major goal of 14 and all 4. now, in order to keep him motivated, he needs to set a new goal. My list for him is here, from top priority to low. 1. Get back Wimbledon crown 2. Win this year's USO to win 6 in a row. 3. Improve his Nadal H2H record in GS. 4. Beat Nadal in French Open. 5. Get at least 7 Wimbledon to equal or pass Sampras 6. Win another French Open to prove the doubters wrong. He needs goals to keep going. If he relax too much now, he could probably slip. This happens to sportsmen. Pressure keeps people going, so there must be some pressure for him.
