I've used the document drawer metaphor in the past. When you start getting paper documents, it's okay to put them in their own drawer and you're done with it. But they keep piling up, and after a while, if you do nothing, you will keep searching through a big pile until you find the one you need. You need to organize them into categories and folders. You need to rethink the way you store them. Or like having a mess in your room.
