My dad said if you become a tennis professional just make sure you get into the top hundred, because you have to make a little bit of money. You make a living so you can pay your coaching and, you know, your travels.

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

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

Oh, my God, I don't think any player can look forward to or expect to a career of so many Grand Slam wins or title wins or being so long at the top of the game.

I did all the right things in so many tournaments. But like I said, sometimes in sports it just goes the other way. Maybe you've already won so much that it evens it out a bit sometimes. I don't know.

I don't mind fans coming up in a friendly, respectful way. That's all part of the fun of being a top tennis player. But if people take pictures without permission, particularly if my children are in the shot, I feel uncomfortable.

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