It's very expensive to be a professional tennis player with all the travel and the flights and the hotels and everything.
The fact is I still have quite a few good years in front of me. I still improve.
I just go out there and fight for every point, and then we see how far I can go.
Young players are starting to come up as well and they will see me as one of the older, experienced ones.
I never give up. Doesn't matter what the score is.
As long as I win I'm doing something right.
