Tennis players Venus and Serena Williams are a force to be reckoned with on the tennis court. The sisters first started playing tennis at age 4. Since then, they have gone on to win the Australian and U.S. Open, Wimbledon and Olympic gold medals. But tennis is not the only thing the sisters have devoted themselves to. Venus started an interior designer company called V Starr Interiors. Serena launched a clothing line called Aneres in 2004. "We get bored quickly. A lot of players have a myopic view, but we know tennis can last only so long. After their careers, a lot of stars say, "What should I do now?" Then they realize there's no money left. We've always had something to fall back on," Serena told Oprah. (Larry Marano/Getty Images for Tide)
