Youth is not a time of life, it is a state of mind; it is not a matter of rosy cheeks, red lips, and supple knees; it is a matter of the will, a quality of the imagination, a vigor of the emotions; it is the freshness of the deep springs of life.
Youth means the predominance of courage over timidity, of adventure over the love of ease. This often exists in a man of sixty more than in a boy of twenty. Nobody grows old merely by a number of years. We grow old by deserting our ideals.
Years may wrinkle the skin, but to give up enthusiasm wrinkles the soul. Worry, doubt, self-distrust, fear and despair - these bow the heart and turns the spirit back to dust.
Whether sixty or sixteen, there is in every human being’s heart the love of wonder, the sweet amazement at the stars and the star like things, the undaunted challenge of events, the unfailing child-like appetite for what-next, and the joy of the game of living.
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.
