The most important lesson that I have learned is to trust God in every circumstance. Lots of times we go through different trials and following God's plan seems like it doesn't make any sense at all. God is always in control and he will never leave us.

I know that they [Jackie Joyner-Kersee, Florence Griffith-Joyner and even Wilma Rudolph] have paved the way and they have been a source of inspiration.

I am a sprinter, and I love to go fast. It's very difficult for me to be patient and follow a race strategy or conserve energy.

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.

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 try to think about my goals. I think about my competitors-I know they're working hard, and if they are, I have to work hard too. I have to be one step ahead of them.

For me, it's really important to be able to compete on the highest level.
