I can have my goals, and I can have my dreams. My goal is to make the finals and improve my position. I want to run all decent races. I don't want to look back and say I ran a terrible race.

I don't see myself as disabled. There's nothing I can't do that able-bodied athletes can do.

To have been selected to represent Team South Africa at the London 2012 Olympic Games in the individual 400m and the 4x400m relay is a real honor and I am so pleased that years of hard work, determination and sacrifice have all come together.

I wasn't happy with my performance at the World Championships in Daegu. I had an unbelievable race in the heats, but misjudged the semi and finished last.

I want to wake up every day and feel that I'm training harder than my competitors, that I'm dieting harder, that I'm recovering better. That's what gives me confidence when I'm lining up on the blocks. I've never gone out to prove people wrong. I just want to be the best that I can possibly be.

I still find it strange, I suppose, when I say to someone, 'Can you just pass me my leg?' But I don't ever think about my disability.

These have always been my legs. I train harder than other guys, eat better, sleep better and wake up thinking about athletics. I think that's probably why I'm a bit of an exception.
