"The lesson of Tiger Woods is that the best way to become a superstar is to start young and get in those 10,000 hours as quickly as possible. That’s why Earl put a club in the hands of a toddler, and why Mozart was composing music before most of us can do arithmetic. However, a series of recent studies by psychologists at Queen’s University adds an important wrinkle to the Tiger Woods parable. The scientists began by analyzing the birthplace of more than 2,000 athletes in a variety of professional sports, such as the NHL, NBA, and the PGA. This is when they discovered something peculiar: the percent of professional athletes who came from cities of fewer than a half million people was far higher than expected."
