1. Setup perfectly to the ball every time (i.e. good ball position, hands lower to promote good posture, proper grip and weight balance)
2. No mental mistakes (choose the right club and the right shot).
3. Actually hit the ball (been losing about 6-12 shots per round due to chunks and mishits).
4. Commit to every shot because every shot counts. I shot 103, 106, then 89 in the first 3 rounds of the year by prioritizing 3 & 4 (and the 89 included someone threatening to pull a gun on the golf course.)
