*Nah. I don't want to get rid of all my stuff.
Also, sometimes you don't need something for years but it's still useful to have.
We don't have long on the earth, I'm not going to waste days and weeks getting rid of every shred of my existence yet*
None of this is Kondo. She is not minimalist - you can keep as much stuff as you like, but it's about keeping only the things you want, not all the other junk we accumulate. Also she doesn't say to get rid of things you don't use for years - if you really want those things you keep them. She also says to do it all as quickly as possible so that you can get on with enjoying your life - if you are thinking about decluttering it's probably because the clutter is getting in the way of you leading the life you want.
Kondo has changed my life. I haven't finished yet, but I am already so much calmer, more organised, have freed up more time and my house is a nicer place to be.
I have previously tried the one thing a day/one bag a week/15 mins a day, etc - those would all be fine if you don't have much stuff but don't work if you have tons of clutter - it would have needed to be something like 5 black sacks a day to make inroads into my clutter. Kondo works because you do a whole category at a time and get rid of a lot at once.
I find it helpful that she goes into the emotional hold that stuff has on us. Thanking everything seems mad, but actually it makes sense when you see it as letting go of whatever emotion it is that has made you hold on to things. THe handbag emptying also works - mine used to be stuffed full of old receipts, pens, tissues and other junk, now I just put what i need in there each day and I no longer have the frustration of searching for things in my bag, emptying it out in shops while i find my credit card, etc.
It's easy to read the book and laugh, and I do understand why it seems odd and funny, but it really can be life changing, and some of the the strange things do make sense when you try them.
