There is a lot of pressure put on me, but I don't put a lot of pressure on myself. I feel if I play my game, it will take care of itself.
I've become fascinated by the idea that it's really achievable to make two or three small improvements in a week and by the end of the year, it's 150 improvements.
I think I owe it to myself and my fans in Britain to play one more Wimbledon.
