"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."
