Never underestimate the power of stupidity to reach unimagined vistas.
I’m not a good teacher of writing. I’m not much of an editor, either. I’m comfortable knowing these things about myself. I’m in the “can do, can’t teach” clan.
When I was on the varsity tennis team in high school, my Dad hired a private coach to refine my game. The coach, Charlie, was well into his sixties. He was heavy set, carried quite the paunch, and his ruddy cheeks reflected Charlie’s consistent dedication to late afternoon cocktails. I doubt Charlie ever won many tournaments, even in his prime, but he had an eye for the mechanics of the game that made him a popular coach. He quickly found the flaws in my strokes and helped me improve my game. Your post brought back memories of Charlie, and other fine teachers I was blessed to experience in my life.
Brilliant and thought-provoking article, but I'm confused by your assessment of the cliche, because it seems to be saying exactly what you say it doesn't.
I've revamped that saying, slighty. "Those who can, do. Those who can't do, work for government."
Yes indeed. Try to take a violin lesson from a virtuoso violinist. The better you are the more effective the teacher will be. In many cases they surmounted obstacles before they have active memories that the student finds daunting. Don’t be surprised if you see some sign of disgust.
