If you're planning only to make money and nothing else, you'll be broke.

If your body is damaged, wounded, it can be fixed, but if inside, mentally, you are wounded you cannot fix it, it's hard.

Age for me is just a number.

When I had no shoes I was comfortable - I used to run barefoot. When I wore shoes it was difficult. To run in shoes was ok, but at the beginning of my career it was hard.

Like some high official, you have to tell your brain: 'Do it. Come on. I have to do it.'

This is what I wanted. They tell me that London is the best field in history. I wanted to be part of that. Because everyone will be there it will be a wonderful challenge for me. You can see the best runners, how they look, how they run. For me to beat the best is what counts.

First, do enough training. Then believe in yourself and say: I can do it. Tomorrow is my day. And then say: the person in front of me, he is just a human being as well; he has two legs, I have two legs, that is all. That is mentally how you prepare.
