Practicing for countless hours before we can be good at something seems burdensome and boring. Maybe that’s why we’re drawn to stories of instant achievement. The monk realizes satori (and Neo learns kung fu); the superhero acquires great power out of the blue; Robert Johnson trades for genius at the crossroads. At the same time, we teach children they can’t master a skill without discipline and diligence. We repeat pop psych theories that specify the exact number hours required for excellence. The number may be arbitrary, but it comforts us to believe that practice might, eventually, make perfect. Because in truth we know there is no way around it. As Wynton Marsalis writes in “Wynton’s Twelve Ways to Practice: From Music to Schoolwork,” “practice is essential to learning music—and anything else, for that matter.”
