I do my best, and that's all I can do.

I have a very close relationship with my parents.

I like Twitter a lot. It is a great way to get the fans knowing another side of you.

The only one I feel pressure from is myself to go and give my all for every match and, obviously, I'm a competitor.

To be the world No. 1 has always been a dream for me.

I'm thankful to be able to team up with a company like USANA that cares about my well-being and I know we can do great things together.

I feel like everything is possible.
