"Age does not bring wisdom. Often it merely changes simple stupidity into arrogant conceit. It's only advantage, so far as I have been able to see, is that it spans change. A young person sees the world as a still picture, immutable. An old person has had his nose rubbed in changes and more changes and still more changes so many times that that he knows it is a moving picture, forever changing. He may not like it--probably doesn't; I don't--but he knows it's so, and knowing is the first step in coping with it."
