Chris Evert, who won 18 Grand Slam singles titles in her career and is a now an analyst for ESPN, says she has earned enough money where she doesn't need to work, but prefers to have something to do on a daily basis. She has two sons in college and one in high school.

“My kids are gonna be like ‘Adios Mom,’ so I better have a life,” Evert told *Forbes*. “I don’t want to just be a lady having lunch, getting manicures and pedicures every day and that’s it. I want to have a passion for what I’m doing.”
