I have considered an additional certification that would be useful. It is only about 6 courses, plus a zillion hours of supervised practice. The work doesn't scare me off, but the local, state programs are limited in size and only start every two years. The private (for profit) ones would cost about $25,000 which I would be unlikely to make up in compensation--even if I work until I am 80 years old.

So, considered aaaand rejected.
