Success is a nice thing because it always means you've taken a step forward and it gives you a sense of pride, which in turn gives you confidence and experience-a positive circle, so to speak.

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.

Before, I guess, mum and dad were everything, but now, in my case, I had two new girls and all of a sudden they're completely dependent on you and there's a third generation. It's a funny shift all of a sudden. You have the babies, you have yourself and then you have your parents.

I always had the dream that, once I became No 1 in the world, that if I had a child I hoped I would have it early enough so the child can see me playing.

My game is a lot about footwork. If I move well, I play well.

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

Hopefully I can just have another terrible year with only the one Grand Slam and that will be just fine.
