Wild beasts and birds are by right not the property merely of the people today, but the property of the unborn generations, whose belongings we have no right to squander.
The best executive is one who has sense enough to pick good people to do what he wants done, and self-restraint enough to keep from meddling with them while they do it.
I must be wanting to be President. Every young man does. But I won't let myself think of it; I must not, because if I do, I will begin to work for it; I'll be careful, calculating, cautious in word and act, and so - I'll beat myself.
The credit belongs to the man who is actually in the arena; whose face is marred with dust and sweat; who strives valiantly; who errs and may fall again and again, because there is no effort without error or shortcoming.
I am a man who believes with all fervor and intensity in moderate progress. Too often men who believe in moderation believe in it only moderately and tepidly and leave fervor to the extremists of the two sides - the extremists of reaction and the extremists of progress.

For us is the life of action, of strenuous performance of duty; let us live in the harness, striving mightily; let us rather run the risk of wearing out than rusting out.
