I would agree with all of your list, and can only think of one other thing to add.....
Don't worry about it!
Over the past few years I have gone for months unable to get into ANY book, be it new and intriguing or an old favourite. As someone who reads for pleasure, for learning, for solace and for escapism, having no reading mojo is pretty much a nightmare. It feels as though a long term and lovely companion has been torn from me at times. But as my fretting about it didnt help me get back to books I had to become philosophical about it.
I am just coming (quietly and slowly) out of a no mojo spell, and am doing it with a book I dreamt of the other night. The dream had scenes from the book, and my copy the book itself was also in the dream - how weird is that? So I have of course made this my book to read.
