You can’t watch your own footwork while you’re running. That’s what a coach is for.

Some things about your own performance are invisible from inside it, not because you are unobservant but because you are busy doing the thing. Another set of eyes is not a verdict on your ability; it is access to a viewpoint you physically cannot occupy. Most improvement stalls at the point where self-observation runs out.

Ask one person who has done what you are doing to watch and tell you what they see. Make the question specific rather than general, so the answer is usable. Then listen to all of it before you start explaining why.
