Spark Joy or Swedish Death Cleaning?

The bathroom remodel is in its final stages. YAY! I'm waiting for the towel bars to be installed, some prints to come back from the framers, AND I'm sorting through all the stuff that was in the old cabinets.

In her book Spark Joy, author Marie Kondo says that you hold every item you are making a decision about: keep, discard, donate, and decide if the item brings you joy. If it does, keep it. Someone gave the book to my younger daughter, and when I stayed with her during her surgery and recovery a few years ago, I read it.  

Nowhere does it discuss things like hair clips. I held one and definitely felt no joy, but I can't throw them out. Sometimes I need them.

And the little cup lid? That doesn't exactly bring me joy, but it does keep Baxter out of my water or coffee or tea, and that makes me happy, so I get to keep it, right? And tweezers and paper tape and silver cleaning cloth? No joy, but I do use them.

I have developed a technique in my own system though,  

and I think it's genius.

Anything I don't know what to do with (top photo is of my sink and cabinet area; bottom is of my husband's), I just move over to my husband's area. He can figure out if the stuff brings him joy, and then he can decide what to do with it all.

Genius, I say.

So I'm not doing the Spark Joy system, and I assume and hope, I'm not doing the Swedish Death Cleaning.

Geeze, who writes books about death cleaning???  And why?
