Growing up with three older brothers and being the youngest and the only girl, my mom always made me tough. She's taught me over the years how to be a strong, independent woman, how to carry yourself in a positive way and anything that my brothers can do, I can do.

When I tell people I'm going to the Olympics, they're like: 'What do you do, track and field? Pole vault? Are you a volleyball player?' No one ever guesses tae kwon do.

It is pretty amazing. My parents, who came from Nicaragua to the U.S. - who would have thought that they would have American kids on the Olympic team? I think that's the epitome of the Olympic dream.

I am very proud of my mom and consider her the most courageous woman I know. With perseverance, sacrifice and hard work, she raised a family of Olympic athletes and gave us the tools and the spirit to succeed. That is something that my brothers and I will always be thankful for.

I've been training super hard at the Lopez Taekwondo Academy in Houston, which belongs to my brother Jean. For me, I think confidence is the biggest thing; it's all mental. I train with the best of the best, including my brother Steven, a five-time world champion who won Olympic gold medals.

My parents sacrificed so much for all of us. It makes me want to give back to them by being the best I can be.

Do not sit next to my mother when she is watching one of her children compete because you will have fingernails down your back. She is a nervous wreck.
