Theodore Roosevelt Quote
We admit with all sincerity that our first duty is within our own household; that we must not merely talk, but act, in favor of cleanliness and decency and righteousness, in all political, social, and civic matters. No prosperity and no glory can save a nation that is rotten at heart. We must ever keep the core of our national being sound, and see to it that not only our citizens in private life, but, above all, our statesmen in public life, practice the old commonplace virtues which from time immemorial have lain at the root of all true national wellbeing.
