“Make it your best Performance” not focus on result/score.

Performance Equation

Ability-Interference = Your Best Golf

Your golf performance equals your ability minus interference.

The next revolution in golf is learning to learn.

Practice to learn, Play to win.

Practice provides specific keys to improving your ability, and presents a different way to think about practicing and playing, which in turn will substantially decrease your interference on the course.  Practice gives you specific methods for improving your skill set and shows you how to translate this improved skill to the course.

First develop the skill, then free your mind for great golf

Better skill = Better confidence

Ability – Interference = Performance
