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

I enjoyed the discipline and solitariness of long-distance running, which allowed me to escape from the hurly-burly of school life.

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.

Take care to sell your horse before he dies. The art of life is passing losses on.

In three words I can sum up everything I've learned about life: it goes on.

If there is one thing in life that I have learned about life it is... it goes on.
