Teaching a course for the first time involves a lot of work on the part of the instructor. Areas such as syllabus creation, lesson planning, quiz/exam making, homework grading, etc. can cause stress because the work must be done from scratch. Therefore, "to-do" lists and excellent time management will lead to effective teaching. Fortunately, as time passes and the class nears completion we are left with a valuable reward in the form of important documents. These documents can be reused over and over again for future iterations of the same course. Essentially, all instructors must experience periods of temporary stress in order to enjoy an easier work schedule for years to come. I would like to point out that the best instructors will take their template documents and add changes as they see fit. It is never a good idea to remain stagnant in our profession.
