I agree with what you said about emotions being contagious, and I think we can pass our stress on to our students if we are not aware of it. Taking regular breaks and making sure I am well fed, had enough sleep, and I took some extra time to plan out my schedule and make sure I schedule in regular exercise, I notice I have a significant amount more energey and patients to interact with the students and give them 100% of my attention and not a stressed out, mess of an Instructor. I can set a better example for my children and my students when I use healthy coping mechenisisms.
