I see your point, but I have to say that when I had prepared a lesson on a certain area of lexis/grammar/pronunciation or on a particular theme, I would keep the lesson plan afterwards. It was often useful, sometimes with very little amendment, for future lessons.

If you teach several fairly standard courses, the the overall lesson plans are often very similar for each group of learners. This is especially true if you are following a course book.
