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 imagination, a vigor of emotions.
It is the freshness of deep springs of life.
Youth means a temperamental predominance of courage over timidity, of the appetite for adventure over the love of ease.This often exists in a man of 60 more than a boy of 20.
Nobody grows old merely by a number of years, we grow old by deserting our ideals.
Years may wrinkle the skins, but to give up enthusiasm wrinkles the soul. Worry, fear, self-distrust, bows the heart and turns the sprits back to dust.
Whether 60 or 16, there is in every human being's heart, the lure of wonder, the unfailing appetite for what's next and the joy of the game of living.
In the center of your heart and my heart, there is a wireless station.
So long as it receives messages of beauty, hope, cheer, courage and power from man and form the infinite, so long as you are young.
When the aerials are down, and your spirit is covered with snows of cynicism and ice of pessimism, then you are grown old, even at 20; but as long as your aerials are up, to catch waves of optimism, there's hope you may die young at 80.
