Do you need catalogs coming into your home, or can you shop online? Use Catalog Choice (
https://www.catalogchoice.org/) to stop them from sending you new catalogs each week. Other catalogs - have a recycling bin right by the door, and make sure that day's mail goes into it if it's really not needed.
We don't get many magazines, but the ones we do get are recycled as soon as we are done reading. We get books only from the library, or on the ipad/kindle, so less book clutter. The kids do have books, which we try to keep on shelves in their room.
We moved recently, and actually still have many boxes in storage, much of which we don't need and are going to ditch. Fancy fruit bowl from wedding we never unpacked? Le Creuset tea kettle? Random kitchen stuff we haven't missed? Gone! It's a lot of mental energy having boxes there, really looking forward to it being done!
