I train very hard, until I am sick. Sometimes I train like a foolish man who has no mind.

I had over-trained. I put too much pressure on myself because I wanted that gold medal too much. If I had trained 15 per cent less, I would have won. I was training like a crazy person. There was a lack of self-confidence and a lack of maturity. An athlete does not only train with his body. He trains with his mind.
