I fell upon this article by Jennifer Gonzalez (known all over the world for her excellent site, “The Cult of Pedagogy”) advising new teachers. It was a great read and reminded me a lot of my ups and downs as a beginning teacher.
Here is the thing about teaching: If you are passionate about what you do, it never really becomes “easy.” It is hard in a different way. It is always emotionally taxing and has its share of challenging days. That being said, education is such an amazingly rewarding endeavor, those tough days are ones that you will come to look at differently when you have those really good days.
