"Good teachers are enthusiastic. The number one quality of a good teacher is enthusiasm. Students often complain that their teacher is boring. Can you recall sitting in a class where the teacher was not enthusiastic, to say the least, about his or her work? Can you recall what a difference an enthusiastic teacher made? What about the same for teachers you've known? Enthusiasm demonstrates passion for one's work. When one is passionate one usually enjoys what he or she is doing and one usually succeeds. Moreover, such enthusiasm is inspiring. Consider some of the world's great leaders. I think you'll agree that two of the most important qualities they possess are energy and optimism. They inspire others to action."
