Eight hours work, eight hours sleep, eight hours recreation

"One of President Young’s daughters recalled that he had taught: “Life is best enjoyed when time periods are evenly divided between labour, sleep and recreation. All men, women and children should labour; all must sleep; and if mental and physical balance is to be maintained, all people should spend one-third of their time in recreation which is rebuilding, voluntary activity—never idleness. ‘Eight hours work, eight hours sleep, and eight hours recreation’ was Brigham Young’s motto.”"
