I've always liked to be on my own, since I was young. I like the sound of a quiet place. It helps me focus.

I am an athlete, and I focus more on the issues that concern me: training, perform, eat, sleep.

Yes, I learned history at school; I know everything about apartheid. My dad, he bought the books about it, stuff like that. But I just move on with my life. It's completely different for me.

I think I have made a difference. I have meant a lot to my people. I have done well. They are proud of me. And that was the main focus. I was doing it for my people, the people who support me.

I got my own sound; nobody sounds like me.

The thing I'm afraid of the most with the 800m is injuries. That's why I don't normally like to run in a group: I prefer to be in front, just in case someone pushes me with their spikes. I don't like stuff like that.
