lessen planning

Why do we need to create lesson plans? Isn't the time it takes to come up with them and, more importantly, to cram them into the requisite forms, merely a distraction from important matters like recovering from teaching all day? I am an off-the-cuff sort of individual... can't you just take my word for it that I know the subject matter, and that I will think of an appropriate and engaging way to convey it to the students when the time comes? What's that? You can't? Well then, I suppose I'd better get back to work.

In all seriousness, lesson planning is vastly more interesting when I know I'm actually going to, you know, teach the lesson. More worthwhile somehow.
