“Nobody grows old merely by living a number of years. People grow old by deserting their ideals. Years wrinkle the skin, but giving up enthusiasm wrinkles the soul. Worry, doubt, self-distrust, fear and despair - these are the long years that bow the head and turn the growing spirit back to dust. You are as young as your faith and as old as your doubts; as young as you self-confidence, as old as your fear; as young as your hope, as old as your despair.”
