There is no better way to learn anything than to teach, whatever the subject matter, one’s specialization or out of it. I say this often and hold it as my credo. I also believe that there is nothing under the sun that is not worth learning. So, it follows that this passion for learning, learning for learning’s sake, is a prerequisite for a good teaching. It is a kind of teaching which also instils in the students a passionate desire to learn and then they learn how to learn.
