The main difference between a drug addict and a genius is persistence. A drug addict insists on instant payoff. A genius is willing to work for years before seeing a payoff. When I teach, at first, I arrange that kids get a big bang reward for very little work. I gradually reduce the reward and extend the time. Eventually kids work indefinitely for subtle rewards — honing skill and precise control.
