Book Challenges

I'm thinking of taking this challenge beginning in January. The reason I'm hesitating is because I tend not to finish challenges of this sort. I'm a 'have-to-be-in-the-right-mood' type of reader, and just because a book is on a TBR list doesn't mean I'll read it. I'm a little rebellious that way. Makes no sense, I know, especially since I'm the one taking the challenge. No one has a gun to my head making me read.
Here's a challenge I began last January. I made a list of books to read for it and then deviated wildly from it. Oh well, at least I read more Irish books than I would have if I hadn't taken the challenge.

So I think I'll take the classics challenge. You only have to list seven books. I'll think about it and get back to you. The challenge may be in only picking seven!
What challenges are you taking right now; book or otherwise?
