I'm about this close to drinking the KonMari kool-aid, you guys. I wasn't so sure for the first half of the book, but by the time I was done, I was seriously considering going through my whole apartment and tossing out anything that doesn't "spark joy." My biggest hang-up is the books--she suggests that you only need 20-30. That's just not gonna happen. I mean, I'm a librarian, so I believe in weeding. But I like my books, even the ones that I'm probably never gonna read. I just went through my clothes, too, since I moved recently. I need some serious help with my komono, my miscellany. 
 I like how this theory also influences your shopping choices, too. It aligns well with my personal theory of "Buy your first choice or buy nothing." (Thanks, Jiro Dreams of Sushi!) If you don't really want it, why bother? Marie Kondo doesn't mention my other favorite tidying technique, but I think she'd like it. I once dated a guy who taught me the trick of "sharing the story." If you're unsure about tossing a personal item, show the item to someone you love and share the story of why it's important. At that point you can feel good that someone else knows the story and you can toss the item without feeling bad. 
 Kondo's enthusiasm and conviction in her methodology are fairly infectious. Some of her sentences are gorgeous, but others seem labored. The book definitely needs cute little illustrations to demonstrate her storage techniques, too. 
 Fittingly, I don't think I'll hang on to my copy of the book if I do go through my apartment. Once I tidy up, I won't need it any more.
