There are a bunch of young players coming up and doing incredible stuff.

It's hard to win Grand Slams.

Playing in a main draw Grand Slam is something you dream about as a kid.

Being the number one seed, you're thinking you don't want to lose in the second round.

USTA helps me out a lot, the Tennis Center. I can't thank them enough.

Some days, obviously, I am like 'Today is not the day,' but you got to push through, especially when my aspirations are to be pro, you can't have any bad days.

All these pros are getting better every day. You just want to catch up to them.

You start to take those opportunities when you do get a wildcard, but also you're allowed to say no - just because you get a wildcard doesn't mean you have to say yes. Some weeks I think its OK to take a wildcard, some weeks its not.

I think my serve and trying to come forward a little more are what I need to work on.

From the ground, I'm pretty solid from both sides. My form really helps me a lot and my backend complements it.

Davis Cup helped me a lot. Being in that great atmosphere and having the chance to hit with top 50 guys everyday, being on the practice courts, that gave me a lot of confidence.

I'm pretty close with a majority of the black tennis players.

It doesn't really matter who I turn pro with. What matters is where I take my tennis.

I mean, sometimes you have to go to work.

I just wanted to play and play and play. When everyone left, I'd stay on the court and hit serves or play against the wall.

My goal isn't to be a top junior. It's to be a top pro.

Without my dad doing what he did, and without me putting in the hours, there wouldn't be any travelling the world or playing with the pros. He's a huge part of it.

I'm trying to... stay humble and keep doing what I do.

If you stop working hard, that's when things get to your head.

Clay... is my favorite surface.

If anything, you just let your racket talk - there's no reason for you to talk if your racket can.

I never try to get ahead of myself because there's nothing that bothers me more than cockiness. I don't think that's necessary at all.

Tennis is my life.

I knew I was going to play pro tennis when I was 12.
