Hey - I was an adult when HP came out and it’s definitely one of my comfort reads.
When I just need something to keep me company - particularly if I’m trying to fall asleep - I’ll put on the audiobook version and drift away ensconced in this little world I know so well.
I have a handful of other books or series (usually series) I feel the same way about and which ones I do all depends on what I need right then.
I do most of my reading via the library. A mix between physical books, ebooks, and audiobooks. Anything I find interesting I add to my library wishlist and when I need something new to read I go through that.
I generally only purchase reference books (craft books, cookbooks, etc.) or books I’ve loved and want to own or books that are in series I’ve already started and plan to continue reading.
So the short answer is I don’t organize my TBR lists 😆. I’m not trying to actually finish it since it’s always growing.
