I haven't had a cramp since '99. That was my only time, in Davis Cup, when I was panicky. I was young. I'm very proud of that. Never pulled out. Never had cramps. Never lost very much because of fitness, especially later on in my career where I knew I've put in the hard work. I've done that. I've been very fortunate and clever as well to understand how I need to work, when I need to work. So I'm very happy to have stayed injury free for so long. I hope I can still maintain a few good years on the tour. I really hope so.

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.

I am very blessed to be able to play tennis, the sport that I love and very grateful for the opportunities to play in the finals of big events, when the season starts you are on the roll constantly and obliged to be committed to daily routines on and off the court.

I feel a bit awkward playing in a red shirt out at Wimbledon. But I don't dislike it.

Having twin girls is a life changer - that's for sure. But I like getting up and changing diapers. It's the things you do.

Hopefully I can just have another terrible year with only the one Grand Slam and that will be just fine.

A man who wins, is a man who thinks he can.
