The more I accomplish, the more pressure I put on myself.

There is a big difference between being good and being great.

Putting on my legs is like putting on my shoes. I understand that's how some people might think differently, but I hope that in London, their perceptions open up.

If the legs did provide such an advantage that some of the people are claiming they did, then there would be a lot more amputees using the exact same prosthetic legs I have, running the exact same times I have - and that's not the case.

You don't call the witness a liar, not while he is in the witness box.

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 made the mistakes not because I'm tired.
