There is a third consideration which will also tend to warn us against loss of time. Our life is a brief span measuring some sixty or seventy years in all, but nearly one half of this has to be spent in sleep; some years have to be spent over our meals; some over dressing and undressing; some in making journeys on land and voyages by sea; some in merry-making, either on our own account or for the sake of others; some in celebrating religious and social festivities; some in watching over the sick-beds of our nearest and dearest relatives. Now if all these years were to be deducted from the tern over which our life extends we shall find about fifteen or twenty years at our disposal for active work. Whoever remembers this can never willingly waste a single moment of his life. "It is astonishing" says Lord Chesterfield "that anyone can squander away in absolute idleness one single moment of that portion of time which is allotted to us in this world. Know the true value of time; snatch, seize, and enjoy every moment of it!" (187 words)
