Having twin girls is a life changer - that's for sure. But I like getting up and changing diapers. It's the things you do.

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

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.

When I think of the Olympics I only think of good things. I think of what a great event it is and what it has done for me and my career, and changed my personal life, too.

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.

To handle that stardom, the red carpets, the photo shoots, people all of a sudden recognizing you and following you in everyday life, it's a bit weird. It's strange, and it can have funny effects on you in terms of do you like it or don't you like it. Some people run away from it, some people embrace it; I found a good middle ground.
