In youth, the powers of the mind are directed wholly to the future, and that future assumes such various, vivid, and alluring forms under the influence of hope; hope based, not upon the experience of the past, but upon an assumed possibility of happiness to come, that dreams of expected felicity constitute in themselves the true happiness of that period of our life. Only God Himself knows whether those blessed dreams of youth were ridiculous, or whose the fault was that they never became realized.
