[On a strained relationship between a tennis champion and her mother:] There comes a time when it's probably not cool for your mom to be your best friend.

I think when you start to do well and get your confidence back, everything becomes more fun. When you're playing with not your full capacity of confidence, I think things get a little tough. I knew I could be doing better than what I was doing. Even though I was ranked 5 or 4 or whatever it was, I wanted to get back to the level I thought I could play at.

If you go to Australia, the Australian Open is on all day long on network TV. There's no way CBS, NBC and ABC would do that. They only show the finals. That's always been the case. They don't want to give the time to the biggest tournament we have in the United States. Any other country, it's everywhere -- front page of the main paper, front page of the sports section. We haven't had that here.

I don't think I should be underestimated.

I come from a family of working women, my mum went to work two weeks after I was born - my parents had no money, there was no choice.

I'm going with the flow. I feel when the time is right to stop, it will be flashing in neon lights for me, like this is it. It could be this year, it could be next year, I have no idea. Anyone in their profession seems to think it's fairly clear when it's the right time. I haven't had that moment of clarity.
