People don't seem to understand that it's a damn war out there.

There is only one number one. It is a lonely spot but it has got the best view of all.

People say I'm around because I have a lot of heart, but I know all the heart in the world couldn't have helped me if I wasn't physically fit.

From where we lived, to practise in St Louis was an hour-and-a-half drive each way, so that took a lot of the time. So really, our lives just took different paths.

That's something a lot of athletes miss - a lot of them walk away too soon. They don't get everything out of their system. They have a lot of what-ifs when they're sitting around later in life. I don't have that. I got all that out of my system. I pushed it to the brink, I loved it, and when I walked away, I'd had enough.

I always insist on my jeans being ironed. Is that a problem?

I like any title with the letters U.S. in front of it. To me, the U.S. Open is the most important tournament in the world.
