When I look at my own career, growing up, I was doing really well at age 11, but it was kind of isolating because back then, people weren't hanging out with me. My mom was always there. She had my back and was like, 'You keep focused. You gotta keep focused.' And I think those kinds of lessons were hard.

As a kid, falling was embarrassing. As I got older, I got used to falling and picking myself back up. There's not a sense of failure. It's of disappointment. You train so hard to not make mistakes. When you do, you're learning from that. How do I improve? How do I get better for the next time? Through every failure, there's something to be learned.

I was improving in the sport at age 10, 11, when I was getting my triple jumps - and it was suddenly very isolating. I was doing really well in competitions, and it felt strange because people that were my friends became almost jealous.

If you ask another competitor, they may tell you they felt very competitive towards me. But I can tell you that my biggest competition was myself. There's only so much you can do, right? There is only so much energy that one has. My focus was on how do I get the best out of myself.

Time travel is such a magic concept.

No one can sustain rage for long. I am still angry and always will be. My dear son was stolen from me and his family to never return. He was killed for profit and lies. How can I not be angry? Sometimes though, the rage comes back.

Leaving southern Sudan as a child was terrifying. It was 1985, and my family and I were trying to escape to Khartoum, the capital in the North, to safety.

I had a very, very interesting childhood, but, oh my, education was the primary focus in our family.
