Well, my 2016 challenge was an epic disaster.
Of my main goal of 60 books, I read 13.
Of my 'winter' sub-goal of five particular books, I read zero. I never even made sub-goals for the other seasons after. I still think it's a good set-up for a reading challenge though, as I like the quarterly challenge aspect and that each season represents a distinct period of time. I just happened to fail miserably the year I thought of using that.
Here's to hoping 2017 will be somewhat better, anyway!
