“How desirable is a proper balance between motion and rest, and how difficult it is at times for us to achieve it. Alternation lies everywhere in nature. Even cows and chickens take time off from producing milk and eggs. Only we human beings foolishly forget these solid well-known truths at times and try to live our lives from crest of wave to crest of wave with never a trough between. We forget that in the trough the next crest builds.”

—Jean Hersey, The Shape of a Year
