I can predict with absolute certainty that within another generation there will be another world war if the nations of the world do not concert the method by which to prevent it.
Those persons are happiest in this restless and mutable world who are in love with change, who delight in what is new simply because it differs from what is old; who rejoice in every innovation, and find a strange alert pleasure in all that is, and that has never been before.
Life is a series of natural and spontaneous changes. Don't resist them; that only creates sorrow. Let reality be reality. Let things flow naturally forward in whatever way they like.
