... any discipline requires being able to remember what you need, when you need it.

For more than forty years, Homer Kelley applied his genius to solving the mysteries of the Golf Stroke. His work yielded 45 mission-critical alignments to be achieved throughout the 12 Sections of each and every Stroke. He codified those alignments as the Mechanical Checklist For All Strokes (12-3-0).

Nine of those alignments are the same: Extensor Action.

So, if you maintain Extensor Action in your Golf Stroke, you will have achieved 20 percent of the Checklist. Similarly, if your goal is to memorize the Checklist -- for immediate reference or for its teaching application with a particular student -- then you have memorized 20 percent of the List.

That leaves only 36 items.

Suppose you took only one item per week. Then, in just 36 weeks, you will have memorized each item in the List. Hopefully, you will have been interested enough to learn more and more about each one during the week devoted specifically to it, especially if you are a teaching professional. Then, you will find yourself looking for ways to apply that new-found knowledge with your students. In this manner, over time, you will come to know each item in the List.

36 weeks.

Nine months.

A human being is conceived and born in nine months.

And, for those willing to pay the price, so can be born a true Authority on Golf Stroke Mechanics.
