Teachers, who are really good create that environment where you can be very satisfied by the process of learning. If you do something and you find it a very satisfying experience then you want to do more of it. The great teachers somehow convey in their very attitude and their words and their actions and everything they do that this is an important thing you're learning. You end up wanting to do more of it and more of it and more of it. That's a real talent some people have to convey the importance of that and to reflect it back to the students.
