Exercise dissipates tension, and tension is the enemy of serenity. I found that I worked better and thought more clearly when I was in good physical condition, and so training became one of the inflexible disciplines of my life.

A man's real education begins after he has left school. True education is gained through the discipline of life.

Running taught me valuable lessons. In cross-country competition, training counted more than intrinsic ability, and I could compensate for a lack of natural aptitude with diligence and discipline. I applied this in everything I did.

I am a vegetarian as well as a passionate anti-alcoholic, because I can thus make better use of my brain.

Life is tons of discipline.

Running is the greatest metaphor for life, because you get out of it what you put into it.
