Maybe one day, people will tell me that I am no longer the fastest runner in the world, but I will still be the one who won nine Olympic gold medals.

I must learn to accept failure, accept the facts and learn from them.

When I run on the runway, I can feel a kind of sprint pleasure, which I have experienced many times and am familiar with, but this time it is much stronger; I feel a freedom, a freedom that I can't experience anywhere. It was a pleasure, an excitement, a pleasure of concentration. That feels great.
