 You know, harder things I've ever done, trying to figure out how to present it within a few lessons and this and that. And I had my producer at the teaching company who was taking the course while I was teaching it to make sure that it made sense. You know, if he could say to me, wait, this doesn't sound right or I don't understand this. So it was a lot of fun trying to put it together for people. And I think they're going to like it.
