We should never permit ourselves to do anything that we are not willing to see our children do. We should set them an example that we wish them to imitate.

When you see a good man, try to emulate his example, and when you see a bad man, search yourself for his faults.

The mediocre teacher tells. The good teacher explains. The superior teacher demonstrates. The great teacher inspires.
