It starts with family - they've sacrificed so much for me, with my parents moving away from each other when we were young, for tennis.

I don't want to be that guy that's either arrogant or rubs people the wrong way.

I take pride being an American.

Tennis is my life, obviously, and it's my career. But it's not the be-all, end-all.

I think clearly I've proven I can play at the highest of levels.

I've got my years on tour now kind of under my belt, and I'm getting the experience and playing more and more big matches, which I think helps.

Any time you can play in front of home fans and the electric crowds in the U.S., it's always a blast.

The goal for the top American isn't the top twenty - it's top ten, top five, number one in the world.

Against Rafa or Roger or Novak, it's about getting over that intimidation, believing you deserve a chance to take them out.

I can count on one hand and maybe a couple of fingers on another the number of players I'll keep in touch with after my playing career is over.

How many players can say they're the best in their country? But it's not a goal I ever thought about.

The more time you spend on tour, around the top guys especially, you see what they do, the work, the preparation, the organization they have going into their training. It all leads up to playing great tennis. It really opens your eyes.

When I was the young guy on tour, I don't think I really grasped what it actually takes to be at this level.

I like to be interactive, engage with fans and all that and I think the route I took, staying at home, is definitely going to help with that.

In the offseason, you can definitely get after it a little more. You can have very intense workouts and not have to worry about a match coming up in a day or two or in the next week.

I want to win singles titles.

I'm a massive golf fan.

I love playing golf, but it's so freaking hard.

For years, I didn't feel like I belonged in the second week of Grand Slam tournaments. I just wasn't good enough. But when the 2016 U.S. Open rolled around, I knew, for whatever reason, I was going to make a splash.

Family over everything.

On the road you can't go hardcore with your workout and lifting and then play.

I want to have the most successful career I can. But the people closest to you are the most important.

I have a lot of clarity out on court of what I'm trying to do, my style of game. That's just building strengths.

I missed my roots, so I ended up buying a home in Kansas City.

I'm going to win or lose a match playing on my terms, playing my game, which is big and aggressive and trying to dictate points. Not shying away from that.

Used to be some liabilities people would talk about in my game. I feel like I have cleaned those up pretty well. Returning was big for me. I think I've gotten a pretty good hold on that.

My goal is to be competing to win tournaments that I'm playing instead of just content with making a quarter.

Obviously, not many people get to be pro athletes and hopefully make it in their sport. So I'm just lucky enough to have the chance.

Playing Slams definitely gives you a surreal view of what can happen, and what you can be.

Having confidence in your physical shape allows your game to get better with it.

I play a pretty physical game, trying to run around and hit a lot of forehands, using my serve, and using my legs on my serve.

There can be some lonely and down moments on tour for sure.

I think that everyone that grows up and aspires to be a tennis player dreams about being in the top 10 and pushing from there and going as far as you can.

On the left side of the court, I am in paradise.

I like to eat and Chipotle will fill you up.

I know the person I am.

In tennis that's the beauty. You can always suit up the next week and play another tournament and always have the chance to win it.

I mean, I think you can always improve every part of your game.

Playing in the U.S. Open is the biggest and most important moment of the season for me.

My game is pretty straightforward, I feel like. If there's a big point I'm looking for a forehand; looking to be aggressive.

There's been a couple places where I always loved playing doubles 100%, and obviously I go out there and give it my all.

I've never considered myself a doubles player. I've just enjoyed playing it.

Grand Slam matches are always tough.

As a kid everyone has dreams of winning their ultimate tournament and being number one in the world.

I love being on the clay. It feels very comfortable to me.

Golf is my main thing I love playing any chance I get.

I grew up watching as much Olympics as I could, checking out all the sports. As a kid, you dream of playing your sport and representing your country and seeing the famous rings.

You're going to lose some matches, you're going to have some bad weeks, for sure. It's part of sport.

I love being from the States and having that pride. But at the same time, there is a lot of expectation.

My mom used to play, so she had rackets around the house. We hit on the garage door for a little while, and then she got mad, so we went to a local racket club and took lessons.
