Part of the lives of many artists is the business of teaching.  For some it is a financial necessity and for others it is an emotional or moral imperative.  Whatever the reasons you have for teaching it does need to be taken seriously, you have an obligation to your students and doing it well can be massively rewarding.
Both Laura and Peter teach and both of them have years of positive experiences, hundreds of students who have had a great time and have gone away with a better understanding of the subject.  Isn't that something to feel warm and fuzzy about!
