The lack of power to take joy in outdoor nature is as real a misfortune as the lack of power to take joy in books - Theodore Roosevelt

Gentlemen: you have now reached the last point. If anyone of you doesn't mean business let him say so now. An hour from now will be too late to back out. Once in, you've got to see it through. You've got to perform without flinching whatever duty is assigned you, regardless of the difficulty or the danger attending it. If it is garrison duty, you must attend to it. If it is meeting fever, you must be willing. If it is the closest kind of fighting, anxious for it. You must know how to ride, how to shoot, how to live in the open. Absolute obedience to every command is your first lesson. No matter what comes you mustn't squeal. Think it over — all of you. If any man wishes to withdraw he will be gladly excused, for others are ready to take his place.

Leave it as it is. You cannot improve on it. The ages have been at work on it, and man can only mar it.

We want men who will fix their eyes on the stars, but who will not forget that their feet must walk on the ground.
