"The four rules of learning are explanation, demonstration, imitation, and repetition. The goal is to create a correct habit that can be produced instinctively under great pressure. To make sure this goal was achieved, I created eight laws of learning: explanation, demonstration, imitation, repetition, repetition, repetition, repetition and repetition."
John Wooden, UCLA basketball coach, quoted from 'There Are No Shortcuts' by Rafe Esquith
