Manners is the key thing. Say, for instance, when you're growing up, you're walking down the street, you've got to tell everybody good morning. Everybody. You can't pass one person.

When I was younger I always wanted to impress, to be good for my country, to make them feel good, and sometimes that meant I didn't focus on myself enough. I learned I had to put myself first. And it's fine because I want for me the same thing that they want for me, which is to win.

Women always find you out when you lie. Always. No matter what, they always find out. They're like detectives.

My coach told me if I broke the national record for the 200, I could run a 100.

I just want to push the barriers and see what I can do and how far I can go. I am just determined and driven.

When I was young, I didn't really think about anything other than sports.

As long as I'm in good shape, you'll always see me smiling.
