Tennis is a huge part of my life, but I don't base my self-value or my self-worth or the quality of my life on my results on the court.

In my mind, I'm always the best. If I walk out on the court (and) I think the next person is better, I've already lost.

When youre on top, youre on top.

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.

Definitely sport matures you, if you let it. It definitely makes you grow up because you have to work so hard that if you can't, then you probably aren't going to have the mental capacity to handle it all. That probably played a role in growing up a little faster than maybe other people.

If you give me a short shot I will attack you. I'm not a baseliner who rallies. I try to get the point over with.

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