Tom Willis, a close friend of Richard Dennis, the father of the Turtles, put it succinctly:
“Are Turtles grown, or can they be taught? Do they have a magic sixth sense or something? The jury is in, isn’t it? They’d be better off having the knowledge implanted than relying on a sixth sense. I think I could take a kid who wasn’t my son and say, ‘Do this, I’ll pay you $50,000 a year, or you’re fired if you don’t exactly follow it.’ He’d beat me every day, every week, every month and every year.”
Two books that back that notion of practice and teaching?
