So, here is the promised review!
Tl;dr: I don't think I'm in fundamental well-being, but I do feel my life is significantly better than before the course. However, I find it hard to say whether this is because of the course, or just a coincidence.
Thanks Kat for writing this! I'll give the finder's course a go in the next iteration starting in April. I'll follow your example, and I hereby precommit to write at least a few sentences of review about the course in the comments here, even if I end up quitting it.
