Famous quotes containing the words time and/or signal:
“Working parents are often told that it is the quality of time, rather than the quantity of time one spends with children, that is significant. Unfortunately, good quality time is difficult to define, to measure, and to make happen on schedule.”
—Joyce Portner (20th century)
“Certainly the effort to remain unchanged, young, when the body gives so impressive a signal of change as the menopause, is gallant; but it is a stupid, self-sacrificial gallantry, better befitting a boy of twenty than a woman of forty-five or fifty. Let the athletes die young and laurel-crowned. Let the soldiers earn the Purple Hearts. Let women die old, white-crowned, with human hearts.”
—Ursula K. Le Guin (b. 1929)
