In high school art class, one term we learned pottery. I can remember the teacher demonstrating how to use the pottery wheel. He was the type to wax on and on about this and that and never get to the point. And it seemed that was what he was doing with the clay.
He had smacked a lump of clay onto the wheel and was demonstrating how to centre the clay. He did it over and over again and it just looked like keeping your hands still. He stressed the importance of having centred clay before moving on. It looked boring and like a waste of time.
