"Youth is not a time of life...it's a state of mind, a temper of the will, a quality of the imagination, a vigor of the emotions, a freshness of the deep springs of life. Nobody grows old merely by living a number of years; people grow old by deserting their ideals. Years wrinkle the skin, but to give up enthusiasm wrinkles the soul. Whether 60 or 16, there is in every human heart the lure of wonder, the undaunted challenge of events, the unfailing childlike appetite for what is next, and the joy of the game of living. We are as young as our self-confidence, as old as our fear; as young as our desire, as old as our despair."
-- General Douglas Macarthur
