In 1974, a shaggy-haired Swedish tennis player named Björn Borg won the Italian Open. He was 17 years old. Weeks later, he won the French Open--becoming the contest’s youngest champion in history, then at 20 years old, he won Wimbledon.
Like many champion athletes, Borg began playing at a young age. He’d practiced hard for several years by the time he started winning titles, but he also had less experience--thousands of hours less--than his competitors at the Opens.
