222,
Here are some comments about my observations…not really a debate.
First some quotes that come to mind:
“Begin with the end in mind” Steven Covey ( 7 Habits) Whatever you are trying to accomplish, know and think about what the goal is. Is the “end” the ball… or the finish?
“Aim high in steering” quote from a driver’s education class I took as a teeneager. The point was new drivers and drunk drivers leaving the pub tend to aim at points very close to the front of the car…and end up weaving all over the road. If you pick a spot far off in the distance to aim for, its easier to go straight.
“Once the decision is made to operate, the rest is purely technical” Alfred Blalock MD, inventor of a complex cardiac operation to cure Blue Baby Syndrome. That quote must have amazed students, that he could reduce such a complicated procedure to 5 words …“the rest is purely technical”…because it took great imagination and years of hard work, and skillful orchestration of several disciplines to be successful. But once he did it, when he saw a sick patient, he could see them already cured in his minds eye, and knew it was a simply matter of steps to get to that goal. Similarly, a guy like Hogan after years of hard work , can stand on hole #6 at Carnoustie, a par 5, and see and feel his drive starting down the left side of the fairway, staying in bounds but avoiding the bunkers, leaving him a second shot to the green. Performing it was purely technical once he saw and felt it, but apparently hardly anyone else could orchestrate their body to do it.
For me, the post impact drill work that showed me some post impact action an feelings was like discovering a tool in the box I didn’t know was there…or finding a room in my house I had been unaware of. This may mean I needed it real badly.
Others, who are already “doing it right”, by happy accident or choice…may not need to learn it.
Now, it is changing my pre- shot planning…I can see the shot options with different eyes, and now my mind and body have different feels for these options based on what I have experienced to accumulate these feels. Even when not playing, I can look off and see and feel how to hit a shot between two trees or telephone poles in the distance…how to start it down the left side and cut it in. Watching TV, my eyes now can see the post impact action of the pros…and I think: it’s almost like they are cheating, hitting it straight because they know how to do this action.
So I suppose it can be said the shot starts in the mind, or wherever feels are stored, and translated to action that includes post impact action. I can’t argue that. But I know I had something wrong for half a century. Much of it was simply thinking the end of the swing was the ball. And it’s like a heard a man say about something else…in this case it would be: you can take everything I have, but not my wife, child , or post impact drill work!
