Excellence is an art won by training and habituation. We do not act rightly because we have virtue or excellence, but rather we have those because we have acted rightly. We are what we repeatedly do. Excellence, then, is not an act but a habit. - Aristotle
Be not astonished at new ideas; for it is well known to you that a thing does not therefore cease to be true because it is not accepted by many. -Spinoza.
Shallow men believe in luck, believe in circumstances -- it was somebody's name, or he happened to be there at the time, or it was so then, and another day would have been otherwise. Strong men believe in cause and effect. - Ralph Waldo Emerson
