According to this little test that Goodreads linked to in their Facebook feed, I would be able to read 52 books a year if I committed to reading an hour a day. This year, I've read 78 books so far, mainly because I've used novels as a stress reliever and an escape from other issues that were bothering me. In a normal year I would have read far fewer books than 52; there have been years where I only read two books. Knowing that, if I set aside an hour a day for reading, I could finish my current TBR list in nine years is comforting somehow.
How long would it take you to read Game of Thrones?
