This was a hard book for me to rate. On the one hand, it seemed to have good advice for decluttering and organizing. On the other hand, it seemed to have good advice for people who live very different lives than I do. I don't mean that I have a more disordered home (although it's a hot mess), or that I have a physical or mental health condition that adds a barrier to dealing with it. It's just advice for circumstances that I'm not in.
A large chunk of the book is about corralling children's toys, and the artwork they bring home from school, and all the other mess that kids spontaneously generate, but I don't have kids. Another section was about organizing sports and yard care equipment in a garage or shed. I have none of those things. I also don't have a laundry room to organize.
Ironically, the parts of the book that could apply to me (paperwork and clothes) are the only aspects of my home that I do have under control.
So, like I said, probably a good and helpful book, just for people in different circumstances than I'm in.
