There is a neat quote in "The Last Samurai" I always liked, "Too much mind".
When I was learning to land an airplane, I was doing that thing exactly, and not landing well at all. This in part was because my lessons were spread out over weeks at times because of having kids to rear. But, I'd over think, over adjust, over compensate. You need to flare just before touchdown and if I managed a solid approach, I'd flare too early, now the plane is up in the air and slowing down too much, so you have to add a bit of power and recover, if you don't just go around (which I did often enough).
I finally reached the point of "not thinking", just feeling the airplane, and I got pretty proficient at it even in a crosswind (which really complicates matters).
I find the same true for pitching and hitting, when pitching I can get consumed with where my elbow is, or my leg raise, whatever, I have to just relax my "too much mind" and let it flow. I can type that way, just think of a word and type it, magically, somehow.
Of late, I've tried to get back into playing the piano some. Long ago I'd play an hour or more a day, and got fairly proficient. I can recall playing and noting my hands and fingers were "doing their thing" and my brain was consciously not paying much attention. I restarted with this Rachmaninof piece that is basically a lot of fairly complex chords, and initially I have to slowly figure them out, now it's starting to come back to me, the chords I see on the page just go to the fingers without "too much mind".
I find the whole thing very interesting, and wish I could control it all at will, but can't.
Our brains are pretty remarkable.
