Once you find that peace, that place of peace and quiet, harmony and confidence, that's when you start playing your best.

I've always been aware that the image you patiently construct for an entire career can be ruined in a minute. It scares you a bit, but that's the way things are.

I love tennis! I've always felt like this because it is such a classy sport with a great, competitive flair to it.

When they [court announcers] say, 'This is the world No. 2,' it just doesn't sound right to me because either I'm No. 1 or I'm a grand slam champion. I'm not world No. 2. I just don't like the ring of it when I'm introduced on court because I've been up there for so, so long.

You can be stubborn and successful or you can give it up a bit and change things around. For me it's important to have a bit of both.

I feel a bit awkward playing in a red shirt out at Wimbledon. But I don't dislike it.

I have two lives, and all the problems I might have, I feel like I drop them once I step on to the match court.
