I bought this book a few years ago and I cherish it, as a call for more clarity, simplicity, lightness in life. There is something deeply liberating in trying out KonMari‘s advice to gather all items of a specific type, see them all together, see the different ages of your life from where they come from, and decide to keep the ones that sparkle joy. This is a very condensed summary of her method, that she explains in detail in the book, with a great deal of thoughtful tips. I am aware that this book is very very popular and that countless reviews have already been made; still, I wish to shout my little +1 for it. One can decide not to answer the call immediately, but could consider specific tidying advice, and improve one thing at a time.
