The New Minimalism borrows a lot from other books/theories. I personally saw a lot of Marie Kondo in the way they divide by category, touch everything and thank items for their service. However, the language is a little more appealing to an American audience than Kondo who I found a tad bit kooky. I did appreciate the emphasis on donating items and living a sustainable lifestyle. All in all I found this a good practical guide to decluttering and minimizing your home.
