Tennis is mostly mental. You win or lose the match before you even go out there.

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.

I most certainly believe that when you're an athlete, that really translates to all sports. You just understand it, your body understands it, and your mind understands it. And you just - it just clicks. I've found that happening when I play other sports. I've seen it, like when I've hit the ball with other professional athletes, and you can see they're just learning so quickly. It's just something that's in their blood. So I think it was in my parents' blood and they understood.

I knew my destiny was to be in the winner's circle. There were times along the way where I didn't make it there. But I felt my destiny was definitely to win big titles, win lots of titles.

Nerves are normal. You can't be cured from them unless you're a machine.

Id like to imagine that in order to beat me a person would have to play almost perfect tennis.

I've learned about employee relations; I've learned about following your instinct. One of the biggest mistakes you can follow is not following your instincts, you know? A lot of times your instincts will tell you what to do if you have a good one. Now, if your instincts are terrible, then you ask for advice. But if you have good instincts, you definitely have to follow them, or else you regret them.
