Wow - old thread revived. I taught wrestling in NZ for five years and was always astounded at the rate of progress of my high schoolers. They were competitive of course, but more than that, when shown new techniques their immediate impulse was to test it out and to try to make it work against 100% resistance, in the true wrestling scenario. No messing about with kata - straight to the point, And that, I believe, is why they learned so fast. More than being competitive and wanting to win, they were just really hungry to learn and to know that what they learned worked. And if not .. how to make it work. And it did work as they came back with several medals in national competitions. Competition can be a great tool for learning ... but fails if it produces conceited arrogance. It works for wrestling because the rules keep it safe.
