I try to update as much as possible. You don't want to be in the past.

Serena and I have done some great career planning, and we're playing really at the peak of our tennis right now. I think tennis has been a sport where people play this insane schedule from 14 years old, so of course at 26, it's over. We've really paced ourselves.

I know it's not the most important thing for me to win the most grand slams and be remembered in this world. I certainly don't have to win satellite tournaments here there and everywhere, I don't have to win at all. Although I do want to.

I believe I live in a black and white. I think things are like either black or white. I don't really believe that much in the gray. I think that there's gray for a lot of people, but I don't live in the gray. I realize whatever action I have or take, it's going to have a consequence -- either good or bad. So I live my life in a way where I don't have bad consequences. I just notice there's a lot people around me just live in the gray. I don't know, for me, I'm just really straightforward.

I don't carry a purse when I fly because I have my Hello Kitty carry-on. I'm the biggest adult supporter.

You learn so much from your parents. We grew up in a home where we were definitely taught to be confident. I definitely give me parents a lot of credit.

The most fun part about working out is being done - getting through the workout, let's be honest. But that feeling afterward? Yeah, that's worth it.
