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.

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.

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.

Maturity is the ability to think, speak and act your feelings within the bounds of dignity. The measure of your maturity is how spiritual you become during the midst of your frustrations.

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 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.

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.
