Can't think of any ultimate reason except "
Steering" (3-F-7-A), the Number One malfunction as Mr. Kelley wrote. Therefore, the "Number One" enemy of golf.
Why do people "Steer", despite of knowing (or not) they are not supposed to?
Can't help!!! It's an instinct, a habit, a way of living, and why golf, as well as life, is so fascinating.
How do you help something "can't help"?
What the hell....? The sun rises tomorrow!!
Without "Steering", golf is boring.

YOU load and sustain the "LAG", during which the "
LAW" releases it, ideally
beyond impact.
"Sustain (
Yang/陽) the lag (
Yin/陰)" is "the unification of Ying and Yang" (
陰陽合一).
The "
LAW" creates the "
effect", which is the "motion" or "feel", with the "
cause", which is the "intent" or "command".
"
Lag" is the secret of golf,
passion is the secret of life.
Think as a golfer, execute like a robot.
Rotate, twist, spin, turn.
Bend
the
shaft.
