Sometimes when you're putting the work in it just seems so, so hard, and you never know when that work's going to pay off.

When I need to push myself, I think of all those nicely polished trophies waiting to be lifted up by the winner - and how that winner might be me.

I'm always on the go. I love doing things until I hit rock bottom. Then I need my 12 hours of sleep, and I'm on the go again.

I don't do heavy weights at all.

Of course, everyone knows my story of being born in Russia and moving to the United States at 7. For a few years people would say, 'Well, she's living in the United States, but she's Russian.'

When I make a commitment I stick to it.

I hit a ball for a living, but I have that passion to keep learning.
