Some of the best lines that I have read in a long time. These are off Walden by Henry David Thoreau.
"Say what you have to say, not what you ought." He criticizes conformity: "If a man does not keep pace with his companions, perhaps it is because he hears a different drummer. Let him step to the music which he hears, however measured or far away. By doing these things, men may find happiness and self-fulfillment."
