There are many ways of getting strong, sometimes talking is the best way.

Nothing can substitute for just plain hard work

I had my moments for sure but I wasn't confrontational. And sometimes you get on the court and you'd find yourself very confrontational. It was all a discovery.

I've been cheered by thousands, booed by thousands, but nothing feels as bad as the booing inside your own head during those ten minutes before you fall asleep.

Sometimes it's just harder to remind yourself about what you're doing and why you're doing it... Other times, you have a great desire for it, but physically you're not responding the way you want. That presents other challenges. Then sometimes it all comes together.

It has meant a lot to me to challenge the best players in the world and to beat them. And it means a lot to me to be out here and fighting for the title and, you know, it hurts not to win it.

In tennis you're on an island. Of all the games men and women play, tennis is the closest to solitary confinement.
