Great geniuses have the shortest biographies.

Nothing great was ever achieved without enthusiasm.

Trust men and they will be true to you; treat them greatly, and they will show themselves great.

'Ah, so you shall be sure to be misunderstood.' — Is it so bad, then, to be misunderstood? Pythagoras was misunderstood, and Socrates, and Jesus, and Luther, and Copernicus, and Galileo, and Newton, and every pure and wise spirit that ever took flesh. To be great is to be misunderstood.

Insist on yourself; never imitate...Every great man is a unique.

Keep away from people who try to belittle your ambitions. Small people always do that, but the really great make you feel that you, too, can become great.

When nature removes a great man, people explore the horizon for a successor; but none comes, and none will. His class is extinguished with him. In some other and quite different field the next man will appear.
