There are really only a few practical tips in the book:
- Don't be afraid to do a big purge. Your stuff is just that, stuff.
- Do the big purge all at once. "Ongoing" tidiness should simply be putting your stuff away, not constantly revisiting different parts of your home looking for stuff you can throw away.
- Look up "konmari folding" on YouTube for a new idea about how to fold and store your clothes. For those who are already fairly tidy, this is the only real "new" idea in the book that may interest you.
- Be affluent enough to have these problems in the first place. None of the advice is for people who are simply slobs, it's for people who have accumulated too much stuff and who feel it dragging down their life.
