One thought that kept coming to 
 me as I read (and took notes): this is so very very Japanese. Appreciate the cultural context. It matters. 
 I can and do appreciate the nuances and quirks of KonMari: giving thanks to your belongings, not burdening (squishing) your things in heavy piles, only keeping that which brings you joy. Imagine if we applied KonMari to our entire life? To only keep friends who bring us joy and help us lead happier and more fulfilling lives? To only continue those obligations which bring us joy? 
 Most might think that's foolish and naive, but hey, I'll be the one living my life surrounded by things and people that make me happy. 
 A fun little read. I'm glad I picked it up from the library and more glad that I didn't buy it because as much I liked it, it's probably not an item that would make it back onto my bookshelves.
