How to Stay Young
　                                          by Samuel Ullman 
　  Youth is not a time of life- it is a state of mind;
　it is a temper of the will, a quality of the imagination,
　a vigor of the emotions, a predominance of courage over
　timidity, of the appetite for adventure over love of ease.
　  Nobody grows old by merely living a number of year, people
　grow old only by deserting their ideals. Years wrinkle the
　skin, but to give up enthusiasm wrinkles the soul. Worry, 
　doubt, self-distrust, fear and despair-these are the long,
　long years that bow the head and turn the growing sprit back
　to dust.
　  Whether seventy or sixteen there is in every being's heart
　the love of wonder, the sweet amazement at the stars and
　the star like things and thoughts, the undaunted challenge
　of events, the unfailing childlike appetite for what next,
　and the joy and the game of life.
　  You are as young as your faith, as old as your doubt;
　as young as your self-confidence, as old as your fear,
　as young as your hope, as old as your despair.
　  So long as your heart receives messages of beauty,cheer,
　courage, grandeur and power from the earth,from man and
　from the Infinite, so long as your are young.
　  When the wires are all down and all the central place of
　your heart is covered with the snows of pessimism and the
　ice of cynicism, then you are grown old indeed and may God 
　have mercy on your soul.
