When I was younger, Jackie Joyner-Kersee was a mentor to me and gave me great advice. The best was to 'work 100 percent, but enjoy every moment along the way.' Sometimes you get so in the zone, you forget to enjoy your passions. I love running—but I also love the movies, relaxing on the beach, shopping and spending time with my friends. Enjoying my life helps me enjoy my running.

I'm an athlete who's very determined and I understand sacrifice.

It was not until the end of my freshman year in high school that I thought I could really have a future in track and field. I definitely did not think I could make it to the Olympics back then, though; I was just focused on making it to the state finals!

I love the relays. Track is such an individual sport, so it's fun to do something together.

I focused solely on the sprints, dedicated my time there, got in the weight room, just really did everything I could to make sure I would be in the best position to run for gold.

Being a role model is a privilege.

There are moments that aren't great. And I think it's amazing for people to be able to have some insight, to be able to see the support system and what really happens.
