My motto is: I'm alive, so that means I can do anything.
I think I can change the game.
I just try to stay positive and focused on the tennis, not let anything get to me, like crazy questions. But I'm tough, let me tell you, tough as nails.
To stay interested in tennis, I have to mix it up with other things.
Tennis is mostly mental. You win or lose the match before you even go out there.
For years I felt that I didn't have enough stamina and then, four years ago, I felt like I was not getting enough air but I was diagnosed with exercise-induced asthma. The medicine for asthma never worked.
