I’ve come around to actually liking having piles of unread books (and yes, for me that means both metaphorical and literal piles of them.) There have been times when I’ve actually “succeeded” in reading through all the books I’ve wanted to. And it’s a weirdly unsatisfying feeling.
Whereas having a variety of books in various degrees of “Ok, maybe sometime I’ll start them” means that when I do have the time and desire to read one, I can just grab one that’s ready to go. And that’s a weirdly satisfying feeling.
