I'm at the top of my game so, when I win or lose, I don't freak out...I don't think we can call it a rivalry yet. There's just to many great players around.

I can't stay No. 1 for fifty years, you know. We'll see what happens.

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

I'm proud to be a symbol like the army knife or the mountains.

When you do something best in life, you don't really want to give that up - and for me it's tennis.

Mentally, I'm not ever going to go away.

I am a very positive thinker, and I think that is what helps me the most in difficult moments.
