I actually decided to stop reading a book this morning! I mean, I don't care to pick it back up again at all. I may change my mind later, but right now it's just not worth my time. I feel a little strange rejecting a book...ususally I try to plow through a book once I've started it, but I've decided time's too precious!
It's liberating to thing about what I'll pick up to read in its place! I've added the Books application to my Facebook profile to help me keep track of my "to read" list, and that's been fun.
