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

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

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

The greatest thing in family life is to take a hint when a hint is intended-and not to take a hint when a hint isn't intended.

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