It's strange for my friends when they see me on TV and in magazines, because the person that they see doing interviews and pictures on the red carpet is not the person that they know.

When you are young, you are a little naive.

After being on the court for six hours, being on TV is very glamorous and fun for me. But tennis is always going to be my priority. It's not going to be this thing when all of a sudden TV will get in the way of that.

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 mean, I think I'm doing a lot better than other people that have had shoulder surgery in their careers. Some people have never come back.

I never really had an idol.

When I need to push myself, I think of all those nicely polished trophies waiting to be lifted up by the winner - and how that winner might be me.
