I love a good challenge!
Last week I was thinking I'd sign up for a solid half dozen or more challenges to really give myself a kick in the butt. Then I reflected on how much time it was going to take to organize all of that, time I could better spend reading and reviewing the HUGE NUMBER of books I've requested for review in January and February (seriously, I have a ton of reviews coming up guys!).
I've decided to stick with just a few challenges right now, and if I stay on top of them, and find other challenges that appeal, I'll add them as I go.
