More time on tools than a typical college experience
Mastering a craft takes thousands of hours. Repetition allows for muscle memory — the point at which we are no longer consciously thinking about the tactile actions we undertake, but our body instinctively assumes them.
We see this in carpenters who are comfortable with a hand saw. They do not have to think about cutting — they saw plumb and square and on the line every time, because that tactile act is no longer considered.
