My family is the thing I miss most on the tour.

Before, I guess, mum and dad were everything, but now, in my case, I had two new girls and all of a sudden they're completely dependent on you and there's a third generation. It's a funny shift all of a sudden. You have the babies, you have yourself and then you have your parents.

I can walk around screaming, 'I have 17 Grand Slams. I have the record here or there.' When you can play for history and you do it, that's what is so really cool, is that you can then be compared to other greats or you've passed another great, even though it doesn't mean you're better than him. But it's just like that moment you've gone into the unknown where nobody else has ever been before.

For me, it's important that a fan can buy something that is related to me. Like in soccer, you buy a shirt and it's got somebody's name on the back. That's kind of a cool thing.

My advice is you've got to make sure you wear the clothes and not [let] the clothes wear you. It's quite simple in a way. Don't wear something you totally feel uncomfortable with, but take some chances. Play around a bit. I felt very uncomfortable in suits when I was younger, so what I just started doing was wearing suits when I was going to dinner. I used to overdress a little bit so I got used to wearing suits. Now wearing a suit is like wearing a track suit for me. So it's all good.

I'm not angry. As an athlete ... you should be open to criticism, and you're allowed to be criticized, because not everybody has the same opinion, not everybody likes the same players. The rankings are quite volatile: Today you're 'great,' tomorrow you're 'not,' but then you're 'great' again. It makes for great stories. Now, I always look at the long term and by doing that, obviously, I can stay calm through the storm.

I have learnt to be even more patient.
