I did this years ago, and stuck to it too. My pile of to-be-read books is now less than 4 (and they're all from the past few months), my books are returned early to the library, and house is much less cluttered (a nice side effect). I used to force myself to read the whole book and now if a book doesn't catch my attention by the 2nd or 3rd chapter, I return it to the library or put it up for swap. My time is too valuable to waste on books I don't care about. Have fun!
