Whether you win a match or lose a match, in terms of your emotions, it's important to be pretty levelheaded.

Women's tennis is getting faster and the girls are getting more athletic, so I need to push myself to become a better athlete. I think 2013 showed me, like a few other years how important being healthy is and how I must listen to my body. During this off season I have been a little smarter on how I train and how I treat my body.

I go to yoga classes and work on my core.

My main goal is to stay healthy because when you're injured you realise how lucky you are to have your health.

I know many of you thought that I would be retiring today, but if I was ever going to announce my retirement it would not be in a downtown Los Angeles hotel with this fairly ugly carpet.

I love getting consumer reports. I think it's one of my favourite things, studying what people have to say about the product and then trying to make it better.

I love playing for my country, getting the support. Especially for the kids and everybody, showing my example of what I can achieve so early. And maybe they can achieve it, too, just to get that in their minds.
