Basketball is an intricate, high-speed game filled with split-second, spontaneous decisions. But that spontaneity is possible only when everyone first engages in hours of highly repetitive and structured practice--perfecting their shooting, dribbling, and passing and running plays over and over again--and agrees to play a carefully defined role on the court. This is the critical lesson of improve, too, and it is also a key to understanding a puzzle of Millennium Challenge: spontaneity isn't random.
Take a random group of 8-year-old American and Japanese kids, give them all a really, really hard math problem, and start a stopwatch. The American kids will give up after 30, 40 seconds. If you let the test run for 15 minutes, the Japanese kids will not have given up. You have to take it away.
