Remember, Rogue, he who can, does, and he who cannot, teaches.In 1981 the Army had a Chinook crash which killed one and cost $8M to rebuild the aircraft and the person who caused it was a SSG (Staff Sergeant) aircraft electrician.
A little over a year later the same SSG caused a Chinook to over speed it's power-train costing another $2 M in repairs so the commander refused him to work on any of his aircraft.
Sooo, the sent him to Fort Eustis, VA as an instructor to teach .... aircraft electronics repair!!! Yep, F-up and move up!
In my life, I've read and heard and seen to a certain extent the best physicists, doctors, engineers, political scientists, economists, who were the worst-ever teachers and practitioners of pedagogy. On the other hand, others who were failures when trying to apply their theories to their trade were huge successes in education. It's how you teach, Rogue, not how you do. Great brains probably expect too much of their students and thereby skip too many essentials. Not generalizing, mind you, as the opposite if also often true.
