I'm just going to post this little guy because chesil said everything I wanted to.
If you're a quitter, Bookjumper, then I must be one, too. I have quite a few impulsive book sale buys that I probably wouldn't have bought if it wasn't for a sudden "got to have books, now!!" that fluttered through my mind. Some of them I've started and liked and then got bored with and gave up on. Some I discarded after the first few pages. I don't feel guilty about them, though. They're just not my taste. Period.
I'll take them over to the second hand bookstore once I have the time, and then they'll bring someone else a bit of reading pleasure.
