Where the heck did all this crap come from?

Ok, busy trying to get the place packed up so I can move it all to the new apartment on the other side of the building. Not worrying about getting everything boxed up because I’m only going to have to take it out of them after moving it practically next door. Still, I’ve got about 15 or 20 boxes cluttering up the living room and that’s only the bookshelves!
Most of the stuff will come off the shelves, closets or cabinets and go right back into them in the new place. The wife wants to box every single item up, but I’m resisiting. Besides, she’s going to be too busy studying to help much anyway.
Yes, we have entirely too much Stuff. Some of it we need to keep, some of it I’m sure we can get rid of and never miss it. The problem is deciding what’s what. Inevitably I’ll pick up something that should go into the crap pile, have a look and then it ends up in the keep pile.
Reminds me of a kid’s book I used to read. Something about a little boy who is supposed to clean up his room, so he gets two boxes, labels one KEEP and the other THROW AWAY. Things get put into the KEEP box, other Things get put into the THROW AWAY box. Then he starts going through the Things in the THROW AWAY box and decides it should really be in the KEEP box (because you never really know when a thingamabob or a doodad will come in handy). And then eventually everything ends up in the KEEP box. What I liked most about the book was the processes the boy went through to decide whether or not to keep the Thing.
Great book. I wish I could remember what it was called.
