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.

Tennis has given me this wonderful life and I'm very grateful for it.

I don't worry about what my opponent is doing.

When you're going through tough moments, you never know when you're going to have good moments.

When you start from nothing, when you come from nothing, it makes you hungry. I am proud of where I came from and I know what I want. I want to win.

I have had lots of luck in my career but there has also been a lot of hard work.

I don't have to follow any special diet or count calories. I try to eat healthily and before a match I load up on pasta and salads. But I pretty much do what I want.
