I've been in a lot of trouble and come out of it. I think it shows a lot of good character.

I'm really trying to focus myself on playing tennis, and I think that's really important.

The serve really is the key to my game.

If I'm going to be out there, I want to be in the top 10 and really have a chance of winning a Grand Slam.

If you serve well, your volleys are going to be so much easier. It has got to do with confidence, obviously.

Once you succeed in tennis, financially you become quite well off.

I played Chang here under the lights here. I think that was '91. Another good match. I've played a lot more good matches under the lights than I played bad. You tend to remember some of the bad ones unfortunately.
