I have learnt to be even more patient.

I don't need to come back to Wimbledon every year because I can't live without it. I'd be totally cool without tennis.

I have two lives, and all the problems I might have, I feel like I drop them once I step on to the match court.

I am thinking more and more about what I want to and can do after my days as an active athlete. Thoughts like family and marriage also cross my mind more and more often.

What I think I've been able to do well over the years is play with pain, play with problems, play in all sorts of conditions.

It doesn't need to be the same every day, doesn't need to be the same shower I use, the same restaurant I go to, the same hour I go to sleep. I've always been very flexible. I don't care if I practice at nine in the morning or 10 P.M.

With all the injury problems we have in men's tennis at the moment, I'm happy to still be standing.
