I have so many different interests in so many areas that sometimes I just need to chill, step back, and let it be.

It's good to have a good teacher, but you always need a pretty good student.

I am always wearing a bracelet, necklace, and watch. I don't even care if they don't match.

With the right set of mind, with the right people, with the right support, things happen.

My dad taught me how to play tennis, and I owe that to him. But the better you get, the higher you climb, and the more lonely you get. I've had to sacrifice a lot of personal relationships, but that's the choice I made.

Tennis players have the ugliest feet.

I like camouflage a lot.

I try and do whatever I want with my free time. I think having control of what you do is really important.

At the end of the day, health above all.

Once the opportunities knock on your door, you've got to try and go get them. If it doesn't happen, it doesn't happen. But at the same time, you've got to keep going.

Sometimes, I have to beat myself first in order to beat the other guy. And that sucks. I'm not gonna lie. But that's me.

As long as I don't overindulge, it's OK for me to eat burgers and ice cream occasionally. As for alcohol? I've never tried it.

I have always been an admirer of Feli, Feli Lopez. He's just - I mean, every time - he's, like, fit and good and his long hair and the beard.

There is always a dream, for me, in the locker room before matches as well during the day. If you have a strong mind, a strong tendency to keep you strong, I think your dream is coming.

I can play on grass - when I won Junior Wimbledon, that was an unbelievable feeling, I could not believe that I had won the tournament, as Wimbledon is like the holy place of tennis.

The majority of decisions, I've always taken by myself.

I don't want to say 'gullible,' but when I saw someone, I always thought that person is the way they present themselves.

Sure, I can afford a nice car and a nice place, but this is not what brings me happiness. Now you're on a high, and people know you and things like that, but how many people will remember your name once it all stops and the money isn't raining from the sky?

My favourite designer was Alexander McQueen. His lines were different every time.

Tennis is great, but it doesn't necessarily define me.

After Wimbledon is one of the only times you can take time for yourself.

One of the scariest things for any athlete, I think, is pretty much the off season.

There is no shortcuts. Play your best tennis, give your heart out, and anything can happen.

I love tennis. But even if I become the greatest of all time, I still don't only want to be defined by tennis. I'm my own person. And I want to be remembered as I really am.

I like to stay away from that red carpet world unless I absolutely have to do it. I'd rather put on my Tom Ford suit and take a few pictures at home.

I'm the kind of guy that I cannot just lock myself in the room and just think tennis for 24 hours.

I'm a very creative person in general. I like to create stuff in my downtime off the court.

I really believe that I can be the No 1, but for that to happen, I probably need to win a couple of grand slams, and they are not going to fall from the sky.

I think the first step is definitely Top 5. From there, you can sort of see the end, and that's the top. In order to do that, you need to win Slams and big tournaments. That's just proven. There is no other way.

I would love to have a beautiful family one day, to win Slams. I'd love my kids to see me play before I retire.

Tennis is my dream. It is what I love. And it is what I want to be best at.

In order to be the best, you have to be around the best.

You're going to play a lot of tournaments during the year, a lot of traveling. If you have a good set of mind, you're committed to the work, you want to do that work, and you definitely got to do it. Doesn't matter if you have four, five, six losses in a row, that doesn't have to discourage you to stop all of a sudden.

I'm just going to have to keep working on what I have to and keep chasing my goals.

I love design; to create stuff from ground zero is the best for me. I'm always so intense when I talk about that.

I think, losses, I think they teach you the most, but it's tough. I'm not gonna lie. It sucks. It's terrible. You can't sleep for two days.

I think 2014 was, like, throughout the whole year, I had this fantastic year.

At some point, you have worked so hard in your life and your tennis that you don't want to be too much up and down. You want to do what you have done and eventually get better.

You've just got to take things the way they are and accept them and strive.

Of course there is a lot of things you can work on and change and all that, but first I think you should look at yourself before you actually start trying to find excuse in the other people, whether it's going to be coach, physio, family, or whoever else is on your side.

Wimbledon is a very special tournament, and for me, it's one of the best events.

You have to forget you are playing against your idol, because the guy on the other side also wants to play better than you and beat you. I don't think you should allow yourself to think like this when you go against any player.

You never know how many times you're going to be able to come out on Rod Laver Arena and just play.

I am always focusing on what I can do better for years down the line.

It's always tricky to play against a player who you've never played against.

One tournament can change everything for you. You never know when that tournament might be.

Tennis is one of those sports: whatever you put in, you get out.

There's a lot of distractions in New York.

I think people enjoy seeing my kind of game.

I'm terrible at relaxing and holidays. For me, a day off is going to the gym. I could never just lie on the beach and read a book.
