When I'm down or maybe when it's close in the match, I feel like I'm still in it. I don't feel like I'm letting down. Mentally, I'm still really, really tough.
I want to be different. If everyone is wearing black, I want to be wearing red.
I go to yoga classes and work on my core.
I don't worry about what my opponent is doing.
I was very disappointed (at the U.S. Open), and I went out there and I worked really hard.
It'll be great. Of course I was disappointed last year. But . . I'll get my revenge.
