What is so great about teaching?

Since I like learning and want to maintain a learning outlook, teaching is a great way to maintain that perspective. Teaching is as much a learning process as it is a 'teaching' or passing on information one. I enjoy communication within the atmosphere of a classroom because the rules of good learning allow many viewpoints to be equally shared and considered. As a matter of fact it is a necessity that it be so and thus many subjects are available to wonder about and inspect. Teaching and learning is how everything happens.
