Many if not most of my fellow golfers spend much of their time overly concerned about the technical details of their swing and how they might improve their game by focusing better on certain mechanical aspects.
Enough of this madness about grips, knees bending, hips twisting, follow-throughs extending. This is a thinking man's sport.
My tactic on the other hand is based more on not so much understanding why this or that works as much as how it feels just right or wrong.
I experience the groove when my swing is right, and the clean strike and straight flight of the ball provide me with the necessary positive feedback. My holistic bodily memory is reinforced so that I just know what to strive for the next time.
The moment I start trying to figure things out and concentrate on some defective mechanical motion of mine, that's when my game falls apart. Just get into the zone and stay there by concentrating on the groove.
If I hit a great chip that ends up close to the hole or a drive that duck hooks into the water, I experience the groove or defect in my body rhythm, thereby knowing what to repeat or what to avoid the next time around.
