Isn't Libby great? Aren't public libraries great? Personally, both my eyes and my mind are better off if I get ebooks on my Kindle rather than on my phone, because the phone itself is part of my attention problem, but there IS something about a due date that encourages me to stick with the borrowed book steadily.

I will DNF a book for whatever reason, but I need to develop more of a sense of permission about it, rather than just guiltily letting the book slip away and glare at me from the shelf.
