Youth is not a time of life; it is a state of mind;

it is not a matter of ripe rosy cheeks, red lips and supple knees;

It is a temper of the will, a quality of the imagination, a vigor of the emotions;

it is the freshness of the deep springs of life.

Youth means the temperamental predominance of courage over timidity, of the appetite of adventure over the love of ease.

This often exists in a man of sixty more than in a boy of twenty. Nobody grows old by merely living a number of yesrs.

We grow old by deserting our ideals.

Years may wrinkle the skin, but go give up enthusiasm wrinkles the soul. 

Worry, doubt, self-distrust, fear and despair---these bow the heart and turn the spirit back to dust.

Whether sixty or sixteen, there is in every human being's heart the love of wonder, the sweet amazement at the stars and the starlike things, the undaunted challenge of events, the unfailing child-like appetite from what-next, and the joy of the game of living.

You are as young as you 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 your heart there is a wireless station, so long as it receives message of beauty, hope, courage, grandeur and power from the earth, from man and from the Infinite, so long are you young. 

When the wires are all down, and all the central places of your heart are covered with the snows of pessimism and the ice of cynicism,

then, and only then, are you grown old indeed.
