Youth is not a time of life;it is a state of mind.
Youth means a tempera-mental predominance of courage over timidity, of the appetite for adventure ove
r the love of ease.
Years may wrinkle the skin, but to give up enthusiasm wrinkles the soul.
Whether 60 or 16, there is in every human being’s heart the lure of wonder, the unfailing childlike appetite for what’s next and the joy of the game of living.
When the aerials are down, and your spirit is covered with snows of cynicism and the ice of pessimism, then you are grown old, even at 20.
