I’ve read this book multiple times, so I think I’ve got a good understanding of it and the spark joy concept still gets me. Basically, it makes you think something must make you soooo happy you only want that thing.

Well I can say that she at least doesn't particularly understand the concept.

This article is basically "I hate the book and the method, I don't understand half of very well, it works super well and I highly recommend it" which is pretty funny, if not exactly well presented.
