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.

Sport teaches you so much, and you can translate that to other parts of life. But it's definitely a lot of dedication, not just for, you know, myself or the children, but the parents, the family finances, the money that you could be putting toward retirement you're using to buy tennis shoes and restring rackets and tennis lessons. So if you don't make it, then you may never retire. It's definitely a lot of risk.

I guess some kids around me had to grow up quickly, had all those problems. But I wasn't one of those kids, or around those kids, not at all.

I don't want to give anyone an edge in my mind. Every time I walk out on the court, I have to feel I'm the best so I can compete well. A lot of times, my chief rival is just me.

To stay interested in tennis, I have to mix it up with other things.

There is nothing like playing at Wimbledon; you can feel the footprints of the legends of the game-men and women-that have graced those courts.

I know it's not the most important thing for me to win the most grand slams and be remembered in this world. I certainly don't have to win satellite tournaments here there and everywhere, I don't have to win at all. Although I do want to.
