Interesting points in both articles. I have done some decluttering and have read many books, including both by Marie Kondo.
What struck me most about reading the post was the realization of privilege involved, the knowledge I have that except for sentimental items, things can be replaced. But that is offset by a perhaps unreasonable fear that in the future I won't be able to replace them.
My husband's parents fled Europe with very little, although they had had a lot. My husband is sentimental about items, his sister is not. His parents had the "right" amount of stuff, but maybe that was because they did not have things from their childhood, or their parents. In my family things were a little tight growing up but I had everything I needed.
I was surprised by Marie Kondo saying she respects other organizers. Perhaps it is the translation of her Japanese that gives the wrong impression. In especially her first book it seems she thinks that only her way is the correct way. It was interesting to see that her second book seemed to acknowledge that it wouldn't all happen overnight, that sometimes you need things that are useful and you can learn to appreciate them, it's okay to keep items in the gray area, etc.
I definitely have more to get rid of, but I will keep more than is often suggested. I love how I am now wearing jewelry I haven't worn for years, etc. and reading old letters makes me happy.
I think I need to let go of more, and also enjoy what I have more. And not let needing to clean up/organize keep me from doing other things I love.
I got off topic, but I have been pondering all of this in the last 24 hours, even before I saw this post.
