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 years; 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 spirit
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 starlike 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
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
you are young.
