All the good stuff is on the other side of tired.

You've got to believe you can win. But I believe respect for the fact that you can lose is what you always have to keep in mind so that nothing suprises you.

You have to have the mentality of executing your game when you don't feel like there's a lot of hope. I think the best feeling is when somebody pushes you to the limit and you dig down a little bit extra. By the same token, you also need a little luck. Sometimes they come together.

Even if it’s not your ideal life, you can always choose it. No matter what your life is, choosing it changes everything.

Now that I've won a slam, I know something very few people on earth are permitted to know. A win doesn't feel as good as a loss feels bad, and the good feeling doesn't last long as the bad. Not even close.

Tennis was always sort of a - a learning. It was a vehicle for me to discover a lot about myself. And the things that I sort of discovered at times I not only didn't want to see it for myself but I certainly didn't want millions of people to see it.

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