"Wayne Gretzky describes his habit, as a four-year-old, of watching hockey games on television with a pen and paper in hand. On the paper, he would draw a rink: the ice surface, as viewed from above. Then, while staring at the action on the screen, and without diverting his eyes to the paper, he would trace the movement of the puck. When play stopped, he would look down at his scrawls and observe what he recalls, in retrospect, as patterns: areas of the ice where the flow seemed to concentrate, and others that his pencil scarcely touched."
