Serena Williams: I don't love tennis

Serena Williams is not passionate about the game she has dominated for so long, but not about to leave it, the 13-time Grand Slam winner said Monday, according to TennisNow.com.

"I mean, I don't love tennis today, but I'm here, and I can't live without it ... so I'm still here and I don't want to go anywhere any time soon," Williams said after her first-round win at the Brisbane International, according to TennisNow.com.

"It's not that I've fallen out of love; I've actually never liked sports, and I never understood how I became an athlete," she said, according to the website. "I don't like working out; I don't like anything that has to do with working physically."

Williams, 30, turned pro in 1995 and won her first Grand Slam title in 1999, at the U.S. Open. She has 39 career singles titles.

Williams has previously been criticized for spending time on interests outside of tennis, such as fashion design and acting. But she explained that her outside interests are actually keeping her motivated to stay in the game, according to the report.

"I just want to be able to do other things I am doing and expand on that -- I think that will help keep my motivation up (in tennis)," Williams said, according to TennisNow.com. "I have always been preparing myself for life after tennis."
