Madison Keys

We do a lot of lifting, and mix it up with upper body and lower body. A lot of circuit training for cardio. I hate just doing long distance running, so I do 5 or 6 different exercises for 20 to 30 seconds then move to the next one.

Everyone else wants to hear 'I wanna be Top 5,' or 'I want to be winning a Grand Slam.' Those are all goals of mine, but I'm not going to put a time limit on them.

I started full-time training when I was 10, signed professionally when I was 14, and won my first match at the same age.

I try to live in the moment and not overthink things because then you start putting yourself in situations that you don't want to be in pressure-wise.

I think the biggest thing is knowing that those thoughts of panic are probably going to go into your brain, and just accepting it... So that's been the biggest thing. Not fighting it and trying to think I'm going to have the perfect mentality the entire time. That's not going to happen.

One night I couldn't sleep at three in the morning and I thought, I'm going to color-coordinate my closet. And I did. There's a whole system. It goes from white to black and then all the colors in the middle. Then it goes by tank tops to T-shirts to long sleeves, and then it goes to the next color. Then it goes to sweaters the same way.

Being an American, we're very lucky that all of the attention is very rarely just on one person. Unless you're Serena - then it's on you all the time.

I loved dance, but tennis felt more natural to me. Dance did help with my rhythm and balance.

I think one big thing for me that I need to work on is being able to separate my feelings and emotions from my matches.

No one who has gotten second place at a Grand Slam is ever like, 'Yeah, now I feel fine about it.' Everyone wants the other trophy. But it inspires you to work harder and get yourself in that position again so that you can use what you've learned.

I would be lying if I said I wanted to wake up and work out every day.

Sometimes it takes work to find a great group of friends whom you feel super comfortable and confident with.
