I love to entertain. I'm not sure every player sees it that way, but I love the performance aspect of it—to be able to entertain people week after week. Some of the happiest times in my life were spent waiting in that hallway in Melbourne, and walking out into Rod Laver Arena with my earphones in and trying to stay focused and drown out the noise but still feeling the energy of the crowd.

What we've done all of these years is very simple, is use the little tool, which is ask three whys in a row. Because the first why you always have a good answer for. The second why, it starts getting difficult. By the third why, you don't really know why you're doing what you're doing.

Could I imagine a world without cursing? Hell, no! Every place I've ever gone, people have had to hold their ears.

Do keep a thesaurus, but in the shed at the back of the garden or behind the fridge, somewhere that demands travel or effort. Chances are the words that come into your head will do fine, eg “horse”, “ran”, “said”.

These tics do bother me. Could I play a match without them? Yes, without some of them. I don't have to touch my nose or put my hair behind my ears before I serve. That's possible to stop. Not putting the bottles in front of my chair, I could go without that, too. But adjusting my underwear, that I could never get rid of. It's impossible.

Playing tennis, competing, winning, but also being at home in Spain, in Majorca, with my friends and family.

Sometimes when I'm in the first round or second round, and I'm not playing well, I say, okay, just accept it. Don't get frustrated. Just accept and focus.

Just normal people from my hometown, from my country.

I don’t think I have one in particular. I am pretty calm. Just some small things that I better not comment on :-).

Selfishness and no respect for the others.
