It is during our darkest moments that we must focus to see the light.

Quality is not an act, it is a habit.

The roots of education are bitter, but the fruit is sweet.

Excellence is an art won by training and habituation. We do not act rightly because we have virtue or excellence, but we rather have those because we have acted rightly. We are what we repeatedly do. Excellence, then, is not an act but a habit. 

It is the mark of an educated mind to be able to entertain a thought without accepting it.
