Youth is not a time of life; it is a state of mind; it is not a matter ofrosy cheeks， red lips and supple knees; it is a matter of the will， a quality ofthe imagination， a vigor of the emotions; it is the freshness of the deepsprings of life.
Youth means a temperamental predominance of courage over timidity， of theappetite for adventure over the love of ease. This often exists in a man of 60more than a boy of 20. Nobody grows old merely by a number of years. We grow oldby deserting our ideals.
Years may wrinkle the skin， but to give up enthusiasm wrinkles the soul.Worry， fear， self-distrust bows the heart and turns the spring back to dust.
Whether 60 or 16， there is in every human being's heart the lure of wonder，the unfailing childlike appetite of what's next and the joy of the game ofliving. In the center of your heart and my heart there is a wireless station： solong as it receives messages of beauty， hope， cheer， courage and power from menand from the Infinite， so long are you young.
When the aerials are down， and your spirit is covered with snows ofcynicism and the ice of pessimism， then you are grown old， even at 20， but aslong as your aerials are up， to catch waves of optimism， there is hope you maydie young at 80.
