It is one of the beautiful compensations of life that no man can sincerely try to help another without helping himself. - Ralph Waldo Emerson

If a man can write a better book, preach a better sermon, or make a better mousetrap than his neighbor, though he build his house in the woods, the world will make a beaten path to his door.

Better be a nettle in the side of your friend than his echo.

Is not every man sometimes a radical in politics? Men are conservatives when they are least vigorous, or when they are most luxurious. They are conservatives after dinner, or before taking their rest; when they are sick, or aged. In the morning, or when their intellect or their conscience has been aroused; when they hear music, or when they read poetry, they are radicals.
