"At a turbulent public meeting once I lost my temper and said some harsh and sarcastic things. The proposal I was supporting was promptly defeated. My father who was there, said nothing, but that night, on my pillow I found a marked passage from Aristotle: Anybody can become angry--that is easy, but to be angry with the right person and to the right degree and at the right time and for the right purpose, and in the right way -- that is not within everybody's power and is not easy."
"Multitudes of people, drifting aimlessly to and fro without a set purpose, deny themselves such fulfillment of their capacities, and the satisfying happiness which attends it. They are not wicked, they are only shallow. They are not mean or vicious; they simply are empty -- shake them and they would rattle like gourds. They lack range, depth, and conviction. Without purpose their lives ultimately wander into the morass of dissatisfaction. As we harness our abilities to a steady purpose and undertake the long pull toward its accomplishment, rich compensations reward us. A sense of purpose simplifies life and therefore concentrates our abilities; and concentration adds power."
"For I say unto you in all sadness of conviction that to think great thoughts you must be heroes as well as idealists. Only when you have worked alone -- when you have felt around you are a black gulf of solitude more isolating than that which surrounds the dying man, and in hope and despair have trusted to your own unshaken will -- then only can you gain the secret isolated joy of the thinker, who knows that a hundred years after he is dead and forgotten men who have never heard of him will be moving to the measure of his thought -- the subtle rapture of postponed power, which the world knows not because it has no external trappings, but which to his prophetic vision is more real than that which commands an army. And if this joy should not be yours, still it is only thus you can know that you have done what lay in you to do -- can say that you have lived, and be ready for the end."
