If there ever was a pursuit which stultified itself by its very conditions, it is the pursuit of pleasure as the all-sufficing end of life. Happiness cannot come to any man capable of enjoying true happiness unless it comes as the sequel to duty well and honestly done. To do that duty you need to have more than one trait. From the greatest to the smallest, happiness and usefulness are largely found in the same soul, and the joy of life is won in its deepest and truest sense only by those who have not shirked life's burdens.
Theodore RooseveltPoverty is a bitter thing; but it is not as bitter as the existence of restless vacuity and physical, moral, and intellectual flabbiness, to which those doom themselves who elect to spend all their years in that vainest of all vain pursuits-the pursuit of mere pleasure as a sufficient end in itself.
Theodore RooseveltIn speaking to you men of the greatest city of the West, men of the state which gave to the country Lincoln and Grant, men who preeminently and distinctly embody all that is most American in the American character, I wish to preach not the doctrine of ignoble ease, but the doctrine of the strenuous life.
Theodore Roosevelt
