The introduction to this book has Marie Kondo saying, “I don’t really see a need for this book. I told you everything in this first book but people keep writing me asking for details on how to do stuff, so here it goes.” I raced through this book and when I was done, I firmly agreed with Ms. Kondo. This book is not necessary nor is it too useful. The tips that I saw in the book I had already seen her give on YouTube videos that I had searched (yes – I admit that I looked for YouTube videos on how she folds clothes. I’m a little ashamed of that, but it is awesome and super helpful). So if you can’t get enough of Marie Kondo, yes go ahead and read this book. But it is, as she states in the beginning, unnecessary.
