This equation is the foundation of everything we do. It was first articulated by Timothy Gallwey in The Inner Game of Tennis (1974) and has since become the most validated framework in applied sports psychology.
The insight is deceptively simple: your performance (P) is not determined by how much potential you add. It is determined by how much interference (i) you subtract. Most coaching tries to add — more technique, more drills, more confidence affirmations. We subtract — interference, noise, judgment, identity conflict.
The result is not a new ability. It is the full expression of an ability that was always there.
