“Practice isn’t the thing you do once you’re good. It’s the thing you do that makes you good.”

“But to play in an international tournament of the caliber announced, he had to spend much more time at careful, precise study, analysis, and memorization. He stopped answering his phone, because he didn’t want to be interrupted or tempted to socialize—even for a chess party—and at one point, to be alone with the chessboard, he just threw some clothes in a suitcase, didn’t tell anyone where he was going, and checked into the Brooklyn YMCA. During his stay there, he sometimes studied more than sixteen hours per day. Malcolm Gladwell, in his book Outliers, describes how people in all fields reach success. He quotes neurologist Daniel Levitin: “In study after study, of composers, basketball players, fiction writers, ice skaters, concert pianists, chessplayers, criminals and what have you, the number comes up again and again [the magic number for true expertise: ten thousand hours of practice].” Gladwell then refers to Bobby: “To become a chess grandmaster also seems to take about ten years. (Only the legendary Bobby Fischer got to that elite level in less than that amount of time: it took him nine years.) Practice isn’t the thing you do once you’re good. It’s the thing you do that makes you good.”
