Women's tennis is getting faster and the girls are getting more athletic, so I need to push myself to become a better athlete. I think 2013 showed me, like a few other years how important being healthy is and how I must listen to my body.

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.
