"The nearer we approach to the middle of life, and the better we have succeeded in entrenching ourselves in our personal attitudes and social positions, the more it appears as if we had discovered the right course and the right ideals and principles of behaviour. For this reason we suppose them to be eternally valid, and make a virtue of unchangeably clinging to them. We overlook the essential fact that the social goal is attained only at the cost of a diminution of personality. Many -- far too many -- aspects of life which should also have been experienced lie in the lumber-room among dusty memories; but sometimes, too, they are glowing coals under grey ashes."
