The greatest joy in teaching has come for me when I know I've made a positive impact on students' lives. I have a few students who have taken the time to write letters of thanks telling me how much they learned in my class and how much they appreciated what I have taught them. Equally rewarding, if not more so, is when a student comes back to me and tells me that she uses what we learned in class all the time! These are the greatest gifts I can give my students and their appreciation is the greatest honor.
