"The point is that thinking, and being able to think, is the only way to make anything BETTER than it is, and sure there's a risk in that but its a hell of a lot better then sitting in one place and trying to hold everything together, particularly when it isn't really quite what you want and you know damned well that its all going to come apart one way or another anyhow. Thinking IS fun ..." This Isn't Just MY Problem, Friend

Find something you think is fun. Play with it, learn about it, create a frame of words/ideas/questions around it, so your students will think it is fun too. And learn from it. As you do.

Have fun. So you can help your students have fun too. Everybody will be happier ... and learn more.

Second day: Add a resources page where you can collect materials you will may use for your lesson. Try and finds things that allow people to have experiences (perhaps interactive, perhaps not) from which they (and you) can develop interpretations/stories that can in turn be modified based on new observations.
