I strongly agree here. It was the subtle things about breath control and muscle-tension control were what I learned while practicing marksmanship.

It is simultaneously true that a person starting out can sometimes see they need guidance to learn the 'trivial common knowledge' that others in a field are already familiar with. These things that seem 'trivial' to experts are things that help them avoid the "many ways to fail at getting good at something while doing it a lot."
