Practice makes myelin, and myelin makes perfect.

Deep practice feels a bit like exploring a dark and unfamiliar room. You start slowly, you bump into furniture, stop, think, and start again. Slowly, and a little painfully, you explore the space over and over, attending to errors, extending your reach into the room a bit farther each time, building a mental map until you can move through it quickly and intuitively.

To sum up: it's time to rewrite the maxim that practice makes perfect. The truth is, practice makes myelin, and myelin makes perfect.

You have to be willing to stop and fix. Deep practice requires a willingness to do what many of us find uncomfortable: to admit to our errors, and focus on them.

Practice makes myelin, and myelin makes perfect.

The solution is to ignore the bad habit and put your energy toward building a new habit that will override the old one.

Baby steps are the royal road to skill.
