Funnily enough, I feel the same way about playing the piano. I'm not a great technical pianist, but with great effort I can teach myself to play the likes of Debussy's Clair de Lune or a movement from Bach's French Suites, etc. At a certain point, my fingers will know pretty much what to do, but then I have to get out of my own way to play a piece as well as I can play it - like, literally daydreaming as I play often produces the best music, and certainly on average better than when I'm concentrating on where my fingers are supposed to move. And sometimes I'll be playing through a piece and I'll know I'm playing it well, and then I'll tense up and expect a mistake which inevitably comes and often leads to further mistakes...which all too often is exactly what happens on the golf course.
