My Classics Club "expires" in March of 2017. That means that I should have read my 50 books in 5 years by then. I'm not going to make it, but I'm pretty close. Close enough for me to be happy. So I'll rework that in March. Right now I think I'll re-sign up (I am a moderator after all), and make a list of 50 books, but keep track of what I actually do read and count those. We'll see what I do in March though.
But for the rest of the Challenges... I like the look of the Popsugar List for next year, so I'll try that. But other than that - I think I'm going on a true book buying ban for the year and will track what I read off my crazy out of control TBR book case vs. what I read from the library. I also like tracking where the books I read take place, so I'll do that again.
I'm also making it a point to read more diversely, so I may also keep statistics on some categories to that end as well. I haven't worked that out in my head just yet though. No matter what, at the beginning of January - you'll see that 2016 Challenges tab turn into one for 2017 and that's where I'll update everything.
So that, in a brief, kind of disorganized nutshell, is my reading challenge plan for next year. Have you thought about yours?
