Hi John,
I know what you mean about having to recharge your enthusiasm batteries. I have been teaching the same course for 5 years and had gotten so bored with it that I took a term off, just to review all of the curriculum and come up with new ideas on how to present the material. I think my boredom was starting to show to the students.
This was the perfect time to take this class ! Now I have more ideas about how important the enthusiasm is and how to bring it back. I do love my field and I want all my students to know it.
