Seemed like folks found some value in the last one so again I steal from The Art of Manliness a bit of poetry by Samuel Ullman called Youth

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 the imagination, a vigor of the emotions; it is the freshness of the 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 sixty more than a body of twenty. Nobody grows old merely by a number of years. We grow old by deserting our ideals.

Years may wrinkle the skin, but to give up enthusiasm wrinkles the soul. Worry, fear, self-distrust bows the heart and turns the spirit back to dust.

Whether sixty or sixteen, 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 the Infinite, so long are you young.

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 twenty, but as long as your aerials are up, to catch the waves of optimism, there is hope you may die young at eighty.

From The Art of Manliness.

We love upright, energetic men. Pull them this way, and then that way, and the other, and they only bend, but never break. Trip them down, and in a trice they are on their feet. Bury them in the mud, and in an hour they will be out and bright. They are not ever yawning away existence, or walking about the world as if they had come into it with only half their soul; you cannot keep them down; you cannot destroy them. But for these the world would soon degenerate. They are the salt of the earth. Who but they start any noble project? They build our cities and rear our manufactories; they whiten the ocean with their sails, and they blacken the heavens with the smoke of their steam-vessels and furnace fires; they draw treasures from the mine; they plow the earth. Blessings on them! Look to them, young men, and take courage; imitate their example; catch the spirit of their energy and enterprise, and you will deserve, and no doubt command, success.
