I am not playing Wimbledon because I am allergic to grass.
I believe the brain is like a muscle - like any other it can be improved.
I have seriously thought about retiring, but that was on a good day. On a bad day I've thought about killing myself.
I certainly don't lose any sleep if I lose a tennis match.
You know how kids are. They like to do what parents do.
Not winning at Wimbledon is not going to bother me forever.
