Tennis is a hard sport. There is a lot of competition all year and you play alone.
My motivation and aspiration is the same, being number one or being number five. So that's the truth. And my goal is the same - it's to always be happy playing, it's to enjoy the game and improve always.
I like a lot of sports. Especially football - it's my favourite sport. My uncle played football in Barcelona for nine years and played for Spain in three World Cups.
I was shy when I was a kid, I was very shy, but now I think I've improved a lot. I can speak OK with the media and with the people. My English is still bad but I feel a little bit better now than before.
The glory is being happy. The glory is not winning here or winning there. The glory is enjoying practicing, enjoy every day, enjoying to work hard, trying to be a better player than before.
I used to wear sleeveless T-shirts all the time on court, but now I've got a brand new look - I've moved on to polo shirts. Sleeveless T-shirts give you real freedom of movement and they keep you cooler in matches, but I just thought it was time for a change.
Last four months were great for me, was probably one of the best four months of my career, playing unbelievable in the clay court season.
I'm ambidextrous when I eat. But playing tennis right-handed - I can't do it. I'm clueless.
I am lucky because my family are comfortably off. My father has his own glass business.
I am decidedly unfriendly during a golf game, from the first hole to the last.
Some people get very confused about my game. They think it's better if the court is slow, because I have a good defence. But the faster it is, the better for me. My spin is more painful for my opponents, my aggressive game works better.
I have no interest in becoming a tax exile and living somewhere I don't want to - I just want to be at home with my family.
If the plane moves, some turbulence, I am nervous flyer.
Why would I want a place of my own? Then I would have to things worry about, like doing laundry and having food in the fridge.
We'll try and be very aggressive, we'll try and speed up and change gears, and we'll see who's going to win.
It's more a tennis problem than a mental problem. The transition is difficult. It depends how much time you have. Playing on grass can sometimes be a bit of a lottery.
In my humble opinion, change is stupid.
Every year I go to Broadway to see a musical - I like the music. I saw 'Mamma Mia;' I saw 'Les Miserables;' I saw 'Phantom of the Opera' like six, seven times.
You fight, you try your best, but if you lose, you don't have to break five racquets and smash up the locker room. You can do those things, but when you've finished, nothing's changed. You've still lost. If something positive came from that, I probably would do it. But I see only negativity.
I'm always searching for new music, and I change what I listen to on a regular basis.
