I am nowhere near the level of expertise of those that responded to this interesting question, but I have spent considerable time pondering how to teach what I understand of TGM to youngsters. I noticed early on that a lot of good things come in threes!
(A). Three parts of a Golf Club
1. Clubshaft
2. Clubface
3. Clubhead
(B). Three Major Concepts of the Golf Swing
1. Inclined Plane – Clubshaft
2. Hinge Action – Clubface
3. Centrifugal Force – Clubhead
(C). Three Essentials for a Good Golf Swing
1. Steady Head
2. Balance
3. Rhythm
(D). Three Imperatives For a Good Golf Stroke
1. Flat Left Wrist at Impact
2. On Plane Club Shaft
3. Club Head Lag
(E). Three Dimensions of the Golf Stroke
1. Downward
2. Outward
3. Forward
(f) Three Universal Planes
1. Horizontal
2. Vertical
3. Inclined
(G) Three Geometric Shapes
1. Circle
2. Triangle
3. Rectangle (the inclined plane)
(h) The Greatest Triune
1. Father
2. Son
3. Holy Spirit
A threefold cord is not easily broken (Ecclesiastes 4:12)
Great list Okie!
Could we add what Homer based it on?
Newton’s first three laws
1. Inertia
2. Force and Acceleration
3. Reacting Forces
I think there is great potential in showing the application of G.O.L.F. (how most touring pros are great with the three imperatives and handicap golfers are not with video examples for instance) and also giving an overview (wetting the appetite for study).

"In my experience, if you stay with the essentials you WILL build a repeatable swing undoubtedly. If you can master the Imperatives you have a champion" (Vikram).
The reason you can't sustain the lag is because you are so eager to make the club move fast (a reaction to the intent of "hitting it far"). So on a full shot you throw it away too early, which doesn't happen for your short chip. (bts)
