"For the ultimate trouble with preoccupation is that it takes no account of the flight of time. Someone has figured human life as covering the span of a single day’s waking hours from six in the morning until ten at night. Then if a man is twenty years old, it is ten o’clock in the morning with him; if he is thirty, it is high noon; if he is forty, it is two in the afternoon; if he is sixty, it is six in the evening. So the day passes and the enriching experiences which fellowship with the Highest offers us are lost, not because we deliberately discard them, but because our time and attention are preëngaged."
