I always start out with good intentions to keep a journal of books read and a short review, but, as the year moves on, I get lazy and don't keep up with it.
This year, I reserved a spot in the List thread and hope to have that as a reminder to keep up with my listing, even if I don't write a short review of each one.
I plan on not purchasing any new books for the first six months. That way I can catch up with my pile of pbooks and start reading a lot of the free and purchased books in my TBR list. That way, if I don't like a book, I can just delete it and move on and it will be out of my library files.
