"Strength is not just the strength of the body; it is the strength of the mind. The strength of the will prevails over the weakness of the body. The will drives the body beyond what the body believes it can do. That is why a great athlete must feed not only his body but his mind. How big was Paavo Nurmi? How big was Sidney Wooderson? He was a solicitor, and in a running vest, he looked like a solicitor, but when he ran the mind was greater than the body." And on and on. And on and on.
