But if you ask someone you meet what the cause of his life's tragedy is, he may say, "O, that I long to have more money; I am very poor, and without resources I am so unhappy." Another person may say, "O, I have everything I want, but my relatives are quarrelsome and very unkind to me." Another says, "I have everything I want but good health." A fourth says, "I have everything, but I long to have a certain peace." Another, "I long to accomplish this art; that big purpose in life; not having done so makes me unhappy.'
