I'm definitely not at my best. Honestly, I'm under 50 percent. But I've won stuff under 50 percent before.

I can't become satisfied, because if I get satisfied, I'll be like, "Oh, I've won Wimbledon, I've won the U.S. Open. Now can I relax." But now people are really going to be fighting to beat me.

I don't think there's anyone besides Venus that could have beaten me at this championship, ... Honestly, I'm playing better than I had in Australia.

I wasn't used to the conditions and...I had to kind of gather myself. When I won the second set I was really relaxed and then I just got a little too anxious in the third and was missing a few shots.

Having a pulmonary embolism is definitely easier than heart break.

I'm definitely picking it up each round, ... I'm definitely playing better than I was even a week ago and two weeks ago. I'm getting better and better.
