Excellence

Pearl S. Buck:
The secret of joy in work is contained in one word - excellence. To know how to do something well is to enjoy it.

Ralph Waldo Emerson:
Is it so bad 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.

Ralph Waldo Emerson:
Build a better mousetrap and the world will beat a path to your door.
