I'm consequently trying to give myself permission to not make the writing-up a Duty.

FWIW, I found it was surprisingly fun to post my list and then ask people to pick a book for me to write up in a comment.

That freed me up to write the "OMFG I have no words for this" responses and the "meh" responses, which I wouldn't have felt made a post in themselves, and generally made it feel less formal and less like "Here is my book report for class".
