Thank you for viewing! This is a very rare book, even within Mercari. If you've been looking for it, please consider this opportunity. ■ About this book This book is written by Yoko Endo, a freelance announcer and certified organizing advisor. It's not just a "how-to book on tidying up," but rather teaches "how to face yourself and design your life." I myself, after reading this book, felt motivated to "sell unwanted items!" and was able to take action. I wholeheartedly recommend this book to those who are not good at tidying up, as well as those who want to organize their lives and bring about positive changes in their work and personal lives. ■ Condition of the product Condition: Read twice.
