SERENA WILLIAMS

SHE STARTED

• She started training when she was 3
• She won her first major championship in 1999
• she won her 23rd Grand Slam title at Wimbledon, defeating her older sister Venus in the Australian Open

Serena's father—a former sharecropper from Louisiana determined to see his two youngest girls succeed—used what he'd gleaned from tennis books and videos to instruct Serena and Venus on how to play the game. At the age of 3, practicing on a court not far from the family's new Compton, California, home, Serena withstood the rigors of daily two-hour practices from her father.

The fact that the family had relocated to Compton was no accident. With its high rate of gang activity, Richard Williams wanted to expose his daughters to the ugly possibilities of life "if they did not work hard and get an education." In this setting, on courts that were riddled with potholes and sometimes missing nets, Serena and Venus cut their teeth on the game of tennis and the requirements for persevering in a tough climate.

In 1995, Serena turned pro. Two years later, she was already No. 99 in the world rankings—up from No. 304 just 12 months before. A year later, she graduated high school, and almost immediately inked a $12 million shoe deal with Puma. In 1999, she beat out her sister in their race to the family's first Grand Slam win, when she captured the U.S. Open title.
