It just occurred to me that Pi-day might be the most appropriate day to make this kind of announcement about my future plans. https://dabeaz.com/next.html
Thanks everyone for the kind words! This is by no means guaranteed--I have to take about 24 semester hours of classes, complete "field work" in HS classrooms, and eventually go through 10 weeks of student teaching. Plus there's the challenge of finding a job as a late career switcher. I like my odds (and math is a decently solid place to be as far as teacher demand), but I definitely don't think it's going to be easy.
At the very least, it's unlikely to be boring ;-).
