Don't feel like you're reading enough? You could resolve to try to more books this year than you did last year.
Or perhaps you might resolve to have some more variety in the books you read. If you've noticed you tend to read books mostly written by white men, you could try and change things up with a Year of Reading Women, like blogger Annika Barranti Klein, who resolved to read only books written by women (with a few caveats) for an entire year. You could also try a year of reading only books by people of colour, or try and read a book by an author from a different country each month.
Graduate Bear won't judge you if you fancy some fantasy instead.
Feeling low brow? You could resolve to read more literary fiction or poetry or finally get to those classics you always feel like you ought to have read but never quite got around to. It might be time to dust off that copy of Anna Karenina and put in some serious reading time to get through it. Or maybe you're over literature and want to resolve to have a little more fun, reading more crime novels, romance or fantasy. If you're finding novels too heavy going, you might resolve to read a short story every day, or every week.
If your house starting to look like a used bookstore or the TBR pile on your bedside table is threatening to fall and crush you in your sleep, you could resolve to finish all the books you already own before buying any new ones (note that this one can be really tricky to stick to if you like to spend time browsing in bookshops).
If you've made any reading resolutions of your own, or are thinking of making some, please share them in the comments.
I don't go as far as reading only women authors or anything, but from using Goodreads l set a goal number of books annually which challenges me, and also pick up numerous books from Little Free Libraries. Those books are usually ones l never would have heard of or thought of reading before seeing them offered for free!
