Thanks for your detailed comments. Glad to see how her book has made a big impact on your habits.

I did find this:

"Kondo uttered the controversial sentence during episode five of season one. In the episode, Kondo visits Los Angeles to meet Matt and Frank, two writers who need her help in tackling their stacks and stacks of books.

While helping the couple to decide whether keeping the books will be “beneficial” to their lives going forward, Kondo states that we should “ideally keep fewer than 30 books”, a practice she follows herself."

As I said in my story- she encourages people to have less than 30 books. I never said she shamed them.
