When the wires are all down and your heart is covered with the snows of pessimism and the ice of cynicism, then, and only then, have you grown old.

Youth is not a time of life - it is a state of mind.

In the central place of every heart, there is a recording chamber; so long as it receives messages of beauty, hope, cheer and courage, you are young.

When the wires are all down and your heart is covered with the snows of pessimism and the ice of cynicism, then, and only then, have you grown old.

Whether 60 or 16, there is in every human being's heart the lure of wonder, the unfailing child-like appetite of 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 men and from God, so long are you young.

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.

Nobody grows old merely by living a number of years. We grow old by deserting our ideals. Years may wrinkle the skin, but to give up enthusiasm wrinkles the soul.
