I think it's because reading became a chore, so I didn't want to do it.
I'm no longer in either the Book Riot Challenge or the Popsugar Challenge, because I'm not going to read because of some theme anymore. I'm going to read because that's the book I want to read.
I'm going to be better about reviewing too, hopefully.
Now, to sneak some reading in between everything else I'm going to be doing with my life, haha.
