Lifetime eclectic at your home course

Many thanks.  I read a lot of those posts.   Man, that is really deep.  As an old beginner, during a lesson or on the driving range, I have hit a good shot, you know pretty straight and it goes say 130 yards (7 iron).  The very next swing, I dig a ditch behind the ball.  I know I didn't do the same things on both swings.  Even this last lesson I had, I would hit a pretty good shot, not so on the next shot.  The instructor would quickly point out, "Hey you stayed on your back foot" or "Guess what happened there.  You got all armsy or handsy".  Sort of feels like I need a checklist when I prepare to swing each time.  I can see it now before every swing, "Hey can you guys give me 10 minutes while I run through my checklist".  In all seriousness, I see what you all are saying.  I wouldn't be overthinking it so much if just I could make decent contact most of the time.  Next lesson is about two weeks away.  Can't wait.

I was going to link in the same think @snapfade did.  Your swing is already consistent, repeatable, except for nearly "microscopic" differences.  The more mechanically-sound your swing becomes, the smaller and less frequent those "microscopic" deviations become.
