I was always really strict on myself about doing everything possible to prepare for competition.

I think I could look back through the past few years at missed opportunities and stuff, but one thing I have learned is not to dwell on missed chances or times where you have failed.

I actually became a Christian in my rookie year on tour when I was 16 years old.

I think Pete Sampras has really reached his peak. About the only thing he doesn't do is cook.

I look at tennis as a bit of a platform to hopefully touch lives and encourage people.

Maybe sometimes I'm such a thinker, I reevaluate too much. Sometimes when it comes down to it, I really don't need to do anything, I don't really need to change anything. I need to just keep plugging away, working at it.

My knee feels good right now. I am definitely able to move about whichever way.
