This rating could change when I actually manage to get fully around to tidying. My "image" for my desired result is being able to take ownership of all my things before moving off to college, so its a little different from long term tidying. That said, I would recommend this book to anyone who hasn't read it, honestly. I think specifically the notes on gratitude are in fact very worth it and a good practice to get into -- being untidy is in many ways treating your things with disrespect, and accumulation of stuff can come from not taking ownership of it. 

A couple pieces of Kondo's advice aren't worthwhile to me personally. Maybe its my lack of hand dexterity but I could never maintain her folding method, and while advice on being willing to go to the store may be useful to hoarders, I see no problem with filling up extra storage, which you'll likely have after only keeping things to make you happy, with essential goods. These don't seem to be the main message of the book though, which is ultimately just being conscious of the items you own, and their meaning to you.
