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.

That's painful always to lose.

The thing, when you're down two sets to love, is to stay calm, even though it's hard, because people are freaking out, people are worried for you.

The family is very important. They make me feel good always because if I won, when I started to be famous, the relationship never changed with my friends and family.

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.

You just try to play tough and focus point for point. Sounds so boring, but it's the right thing to do out there.

I learned during all my career to enjoy suffering.

I don't have any idols, any heroes, nothing, no.

I always wanted to be honest with myself and to those who have had faith in me.

I'm really, really emotional.

I tried to find a solution to the problem that I had, tried to find a way to start playing better.

I'm ambidextrous when I eat. But playing tennis right-handed - I can't do it. I'm clueless.

New York is a special place; it's a city that I love.

I would love to learn other languages, maybe French? My uncle speaks German so maybe also German? Chinese seems to be too difficult.

I love the crowds in Miami. I feel that is one of the tournaments where I get more support. That helps me a lot.

I am not the most courageous guy in the world outside of the court. Being alone in the dark is something I don't like.

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 only ever run when there's some point to it - say, if it's in a game of tennis.

I think the tennis is only a game. You can lose. You can win. After that? In life, there are much more important things than tennis.

I always had the theory that the most important thing is be happy, enjoy what are you doing, and be fresh mentally.

It's not the time to look for excuses.

I will do as I usually do. Tomorrow is going to be a day like any other day.

I always work with a goal - and the goal is to improve as a player and a person. That, finally, is the most important thing of all.

As a tennis player you can win and you can lose, and you have to be ready for both. I practised self-control as a kid. But as you get older they both - winning and losing - get easier.

I appreciate a lot in this life; the things you cannot buy. Life is only once. I am happy being here and all the things that are a risk I normally avoid.

If you don't lose, you cannot enjoy the victories. So I have to accept both things.

My motivation is tomorrow, just one day at a time, right?

I like fishing. Not actual fishing - I like the peace and quiet of being at sea. It's different.

I love the beach. I love the sea. All my life I live within - in front of the sea.

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.

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.

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 was passionate about soccer. I still am. Odd, though - playing soccer always made me much more anxious than playing tennis. On soccer days, I'd be out of bed by 6 in the morning, all nervous. But I was always calm when it was time for a tennis match. I still don't know why.

It's important to have people around you with enough confidence to say if you are not acting in a good way. Normally, when you are at the top, people say everything is fantastic. Probably in that moment it is what you want to hear, but it's best to be reminded how to act properly.

I admire a lot of people, but in terms of sport I've always loved the mentality of Tiger Woods on a golf course. I always love his eyes when he's setting himself and focusing on his decision; he has a really strong, focused face and believes that he can make the shot.

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.

You know, a lot of things changed. What never changed is the illusion to keep playing tennis, the illusion to keep doing well the things, and the illusion to be in a good position of the ranking and play these kind of matches.

I've stayed calm when I'm winning and I've stayed calm when I've lost. Tennis is a sport where we have a lot of tournaments every week, so you can't celebrate a lot when you have big victories, and you cannot get too down when you're losing, as in a few days you'll be in the next tournament and you'll have to be ready with that.

I always like to do the things that I think are right. I am not trying to be a model, I am trying to be myself and do the right things. If what I am doing is a model, or is an example, is the right example, I am very happy, but I don't pretend that.

Being home alone at night makes me a bit nervous. If I'm at home alone, I have to sleep on the sofa - I can't face going to bed. I'm there with the TV on and all the lights on. I'm not very brave about anything in life. In tennis, yes. In everything else, not very.
