I think every athlete that’s just out here for the Olympics just does something to inspire those around them and inspire each other.

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

It's impossible to make everyone happy. Some will choose to see the negative. None is perfect but find a way of loving them perfectly!

I am also hugely excited to then be competing to defend my three Paralympic titles at the Paralympic Games. I believe we will see some amazing times posted and I am very much looking forward to what will be an incredible Olympics and Paralympics in London.

My parents didn't give me any scope to feel sorry for myself. They were just like 'go play with your brother, go climb a tree, go fall off your motorbike, do whatever you want. Don't come crying to us when you get scratched. You've got prosthetic legs - that's very nice.

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.

You're not disabled by the disabilities you have, you are able by the abilities you have.
