My wife and I both have what we call our reading lists, which are the books we most immediately want to read. Originally, mine occupied one shelf of a bookcase. It now occupies two shelves, two rows deep in some places. I've been adding books faster than I am reading. (Which is why I also call this my "good intentions" list.)
So I have two problems. I am not reading as much as I'd like to be, and I buy too many books. OK, so there's no such thing as too many books, but I need to take a break. So until I have read every book currently on my list, I plan on not allowing myself to buy any books (gifts are always welcome, of course), aside from graphic novels. (I only started reading comics in the past few years, and don't have many yet, and I don't want to deprive myself of them while I do this.) I took the time to put all the books into my empty Goodreads account. There are 56. My goal is finish these by the end of the year, which is probably unrealistic. But it's good to set a goal. There's history, memoir, biography, short stories, sci-fi, fantasy, three books about the OED, and more mixed in there. I shouldn't be bored.
Now if you are scoffing at that figure of 56, I have far more than books in our apartment that I haven't read and want to. Those are just the tip of the iceberg, the ones that I've been setting out. Once I clean those out, I can get to the back catalog.
