To be a well-rounded person and know what's going on in the world around you, to have a perspective outside of your sport, is important for every athlete. I'm blessed that our parents gave us that.

Tennis is mostly mental. Of course, you must have a lot of physical skill, but you can't play tennis well and not be a good thinker. You win or lose the match before you even go out there.

I think I've been fortunate to be at the top of the game and in the media for years, and a lot of times, people want to be your friend when you're on the top. You know, there have been times when I've been injured and I never got a phone call. So that's the way it is.

Everybody's got their problems. The important thing is not to complain about it.

I LOVE RIHANNA. I LOVE THAT SHE IS HERSELF WITH NO APOLOGIES. HER SENSE OF STYLE AND SELF IS UNIQUE. I LOVE HOW SHE TRANSFORMS HERSELF WITH EACH ALBUM, EACH CAMPAIGN. ALWAYS EVOLVING. A TRUE ICON.

I don't come to tournaments to make friends, to go to parties, to hold conversations. I come to be the best, and I'm not mean and cruel and dirty.

My first job is big sister and I take that very seriously.
