Only that day dawns to which we are awake. – Henry David Thoreau

There was George, throwing away in hideous sloth the inestimable gift of time; his valuable life, every second of which he would have to account for hereafter, passing away from him, unused…. sprawling there, sunk in soul-clogging oblivion. – Jerome K. Jerome, Three Men in a Boat (To Say Nothing of the Dog), 1889
