At the end of the day, you just have to focus on winning. No one can take a win away from you. That's what I focused on. Life is not fair, so I don't go out there expecting it to be. I don't think any of us should go out expecting life to be fair. I think that's expecting too much, and I remind myself of that sometimes. You can get on with your life after that.

Grand Slam losses are hard. I treat myself after losses though, I usually go to McDonald's and I have a hamburger and you know, something. Because you know, you just need to be nice to yourself sometimes after the loss.

My motto has always been that you can't say, 'Oh, it won't happen to me.' You have to say, 'That can happen to me.' So always be aware that things can happen.

You know, growing up my - you know, I came from Compton, Calif., and, you know, it was a place where a lot of people did come out when a lot of people stayed. So I've been able to see the top and the bottom of life, and I think that balances you if you allow it to and if you remember where you came from.

If you're not a competitor, you've just got to go home.

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.

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.
