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.

My goal is always the same: to keep the other player from ever scoring a point. That doesn't always happen, but that's what I try for.

If I cared deeply about what people thought of me, I probably would have never made it out of Compton, California.

I know I'm good at tennis. Other than that, everything else is a wild card. I'm a wild card.

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

If I go down, it's never easy. At least my opponent knows they have to go to the end of the earth to take me out no matter what the circumstances. I do try to compete. Even if it's not your best day, I just try to walk off the court knowing I gave 100,000 percent.

It wasn't like I was self-motivated. My dad started me. It was his dream before it was mine.
