I abandoned my challenges months ago, as they just weren't happening this year.
I'll have to do much better next year, as my topic challenges are really the point.
What is starting to get interesting is that I'm currently on track to hit 150 books and over 50,000 pages read, neither of which I've managed before. My benchmark goal of 120 was always just to keep a check in case my reading fell off too drastically, but 150 was always out of reach. The number of pages read is in part to keep it real; shorter books need to be offset by longer ones.
