I'm ready. I taught AP Physics 1 and 2 last year in a double period every day (90 or 100 minutes, depending on the day). They did well. They were interested and thoughtful about the material. They did well on the AP exams.
I'm set. I looked through through all my materials, making some edits. I like most of my labs. Many of my questions I assign allow great discussions. I'm excited for this coming year.
I'm scared to make the commitment to a 180 blog and make it public. There are a lot of things I could improve. So I hesitated to start this blog. But I'm often ready and set before I feel ready and set.
