Lopez and two of her brothers—Mark and Steven—made history in the 2008 Olympic Games in Beijing as the first family to have three siblings on the same U.S. Olympic tae kwon do team. To boot, eldest brother, Jean, led them as their coach. In their new book, Family Power, the Lopezes detail their efforts and their parents' support in helping them succeed. Diana shares with Oprah.com how years of hard work, determination and unwavering support in each other led them to earn medals in the sport, with Jean coaching them to victory.
Diana Lopez: My parents came from a Third World country [Nicaragua], and they only spoke Spanish. Instead of going to Miami or someplace where a lot of Latinos were living, they went to New York City. I don't know how my mother did it. My dad was in his 30s, and she was in her 20s. They had to start over. My mom's philosophy was that [America] was where they were going, and once they got here, they were going to do what it took to make ends meet. To this day, my parents don't tolerate complaints. You work hard, no matter what. If you're going to be a custodian or work in a fast food joint, you're going to be the best in whatever you choose.
ES: Tell us about your early days of tae kwon do. I understand your father enrolled Jean to help build his self-confidence. Was it an immediate love affair with the sport for everyone, or did that passion grow over time?
DL : For me, [tae kwon do] was something that I thought I was supposed do. No one actually asked me if I wanted to do it. I didn't know anything different. What I enjoyed most at first was getting to travel to different states with my family. That was our vacation. We'd have to make up games on our road trips. It was fun hanging out with my family, and I'll cherish those moments forever. My dad was always into martial arts. And when were growing up in New York, there was a school across from where we lived. Jean fell in love with it and paved the road for us. We all fell in love with it then. It's weird, because I see different families, with siblings who all play in the same sport, so I think it's something in your genes!
ES : Siblings always play varied roles within a family. What are the roles that each of you played? Has that dynamic helped you achieve such feats?
DL : My brother, Jean, is the top of the pyramid. He paved the way and made it easy for us. He was the one who moved to the Olympic Training center early to teach us things we didn't know in our sport. He really is like a second father, coach and a guidance counselor. Steven is our hero. He's won two Olympics and five World Championships. If I ever have a question about tae kwon do, I ask him. Mark is our superstar, the showman. He plays with the crowd. I'm just the baby only girl, and my brothers say I'm the princess, but I don't think so.
ES : In your book, you talk about the "doubters" and people who didn't believe in you. What was the point where you realized you had to be each other's biggest cheerleaders because of the negativity you faced?
DL : You'll always have negativity everywhere. That was something my parents taught us. But if you don't trust your own family, who will you trust? For me, any negativity motivated me, especially those who would question if I was as good as my brothers. Sometimes it was even my brothers who asked it. But if they slept in, I'd go run. I've always worked extra hard. Overall, we always had support for each other and kept each other going. If I was tired, Steven would grab me to go work out. We never knew if we'd have that chance [of competing at the Olympics] again.
