People may say I developed an iron will, but what really happened is that I made myself much fitter. I think an iron will is always supported by fitness.

Because in order to beat Jimmy, I had to get around the ball a little bit quicker so I wasn't always on defensive and catching the ball on last stride, that I had little more time. Once I was able to get little bit quicker, then it has helped me a lot.

I was between 2 and 3 in the world for two, three years. That's not exactly where I wanted to be.

You know how kids are. They like to do what parents do.

If you look at any superior athlete, you will find a strong parental influence. Parents introduce their children to a sport, and then they support them.

If you lose, it hurts, but as long as you have fought hard, you can still feel good about yourself.

I certainly don't lose any sleep if I lose a tennis match.
