For a while, I didn't really know if I wanted to read about KonMari or not, but luckily I decided to choose this, largely due to Emily's review down here at the reviews (which says this is a expansion to her previous book, with some things explained a bit clearer, and there are illustrations to the folding styles Kondo recommends).
I think there are some books that just work better when you read them instead of audiobooking them, mainly because you can reread and find places a bit better, no risk of unpleasant or fast reader, and all that underlining, stickering of important bits, etc. I did have to pause now and them to breathe (haha) and to absorb a bit, but the subject was interesting enough that I read it faster that just the routine amount I make myself read of a book daily (about 41 pages). I made a bunch of notes for later, and will rewrite them into a clearer form at some point.
I love the rubber band that comes with this hardcover. You can use it or not, but it does look nice when it's used. Just the kind of touchable bonus I like.
This is somewhat different from minimalism-tidying (which aims for smaller amount of possessions) and usual decluttering techniques (in the idea of 'spark joy'). The focus is more on what you really want to keep, with putting in place coming afterwards for everything left. The folding illustrations are mostly concentrated in the clothes section, with one or two in other places. Advicing clients on tidying their homes is the author's work in Japan, and then there's her books.
The point is to keep what 'sparks joy' when touched/seen, for you - others might give suggestions, but the final decision is yours. Knowing where to keep them also helps, but it doesn't come first. Some client/personal examples are given, but they don't disturb the main purpose of the book. It is helpful if you feel already ready to commit to this (even if it doesn' t happen immediately - like, for me I will probably be more likely to start on it after weight loss, since clothes appear first in tidying order).
First the six basic rules of tidying are given, before we move on to the main text (commitment, knowing what home look you want after, discarding in every category before proper arranging, going by categories, in right order, and the 'spark joy' testing). Don't let her insistencies put you off, some of it will end up making sense later.
In the main part: the first part talks about the concept of joy and finding motivation, the second goes deep into each category (clothes - books - papers - komono (misc. items, in smaller categories) - sentimental items). The third part shows the end result for each part of home, and what changes might appear afterwards, plus other people and this tidying process. The main positive impact for this tidying method will be for your mental well-being, which might improve also your outer life (like relationships).
Some tips are a bit outside the main KonMari method of tidying, at least I made notes of them to separate notings (for example, checking on the expiring dates on some emergency supplies, or cleaning your suitcase outside and wheels after traveling).
Of course there are things that are odd or even a bit irritating. For example, I disagree with the opinion that just not have yet read a book is a sole reason for discarding it. And no, I won't cut or tear a page off a book - I would do that for magazines only. And sometimes I prefer piling, not standing up, things. And you do have to be careful with what papers you discard - I think it's better to research first what the lenght of keeping is for some before letting go of them.
She seems a bit optimistic about avoiding relapse back to messiness, and also about how after tidying other things in life get fixed too. Her talk about things' feelings and thanking them too is quite odd, but in my opinion these moves appeal to the part of self in one's head that still can't help but think object have 'feelings'). And anyway, you can freely ignore the odd bits.
But for all the weaker bits and things I disagree with, I'm surprised how much I liked the book as a whole, and the method of tidying started to make sense, the further I got into the book. The client/personal examples made the reading lighter, and gave one some amusement too. I might not get into this right away, now, but I can see myself going through it when the time is right. A rewarding experience that made me think, amused me, and inspired me.
