What about playing musical instruments like learning guitar? Wouldn’t that constitute a habit that becomes automatic after enough practice?
Not for me. I’ve been trying to learn an instrument for several years. I can make it maybe a few days at a time before I forget to keep doing it. If I’m very persistent I can get in enough days of erratic practice to learn a short song.
Playing short sequence of notes is kinda-sorta automatic as in I don’t have to think about all the details of positioning my right hand (it’s a bit like touch typing on a keyboard, I don’t have to think about the individual letters), but that’s about the maximum level of ‘automatic’ I’ve been able to achieve. Finger placement for every chord is completely conscious, every key change, placement of emphasis, etc., all deliberate, conscious actions.
While it’s kind of satisfying to make it through a piece, it’s not relaxing in any way. I keep hoping that someday I’ll get good enough at it that I can make it through at least one song without needing to think about each step, but it’s slow-going.
