Theodore Roosevelt Quote
Our country has been populated by pioneers, and therefore it has in it more energy, more enterprise, more expansive power than any other in the wide world. [...] They have shown the qualities of daring, endurance, and far-sightedness, of eager desire for victory and stubborn refusal to accept defeat, which go to make up the essential manliness of the American character. Above all, they have recognized in practical form the fundamental law of success in American life—the law of worthy work, the law of high, resolute endeavor. We have but little room among our people for the timid, the irresolute, and the idle; and it is no less true that there is scant room in the world at large for the nation with mighty thews that dares not to be great.
