Our house is hopelessly cluttered but we are moving soon so now is my chance to start afresh by chucking out a load of stuff instead of carting it all to the next place.
I have come to the realisation that one of the reasons there is nowhere to put the kids' toys is that I have kept practically every book I have ever read. Lots of them are popular paperbacks like Bridget Jones or whatever but also classics, history A-level textbooks or things like long unread parenting books / books about knitting or whatever.
What does everyone else do? Chuck anything you won't read again? Keep only the "good" ones? I don't want to live in a house without books but there doesn't seem to be much to be gained from holding onto the Kite Runner or Anita and Me or Cloud Atlas or whatever. But it's sad to get rid of them too!
