Motor controls are interesting like that; it's (to my layperson's understanding) a subsystem of your brain close to the brain stem / spine that allows your brain to skip conscious processing for (fine) motor controls. And it can be trained. It's what allows us to learn to play an instrument.

Take drums, put an amateur behind it and it's all over the place, but learning it is (simply?) a matter of slowing down until you can think about every strike, repeating, then slowly speeding up. The movements become almost automatic.

I'm sure something similar happens in 'higher' brain functions, but it takes longer; a common saying is that it takes 6 weeks of conscious effort to form a new habit.
