Sounds simple enough! Although 2 books a month... erm. That will depend on how long the books are, right? You may need to change it to a number of pages rather ;)
We are not keen on "resolutions" though, it's too much of an all-or-nothing game, too rigid and inflexible, so for those who actually want to try something and are tired of failing, why not skip the resolutions altogether and try these New Year's Intentions instead. Happy New Year 2018!
