These were the moments when I was disappointed and frustrated, when I got so low because it seemed all my hard work had been wasted. But the moments passed, and the motivation to go back to rehab was there again.

I know that I'm going to have to work hard, keep working hard, and not because of this victory think, 'I'm back.' I don't think like that. I'll definitely work hard. Things are not going to be easy. I might lose first round next week. You never know.

Physical rehab is often very, very hard work.

Doing all those tedious things in rehab made me more disciplined and focused on the things I have to do for my tennis.

My career has been successful, but it's been a grind of hard work.

Hard work is not why I have been successful as a model.
