Honestly, I read this because my mom heard the author talking about the subject of the book on a podcast and bought it for me. I wasn't necessarily excited to read it because I haven't been in the mood for this sort of book for a while, but I wanted to honour her excitement and give it a try. I enjoyed the set-up. I relate to the topic as someone who has always tended toward the melancholy/sensitive/emotional, and definitely passed the test she created (by a lot). But as I got deeper into the book, it didn't feel that interesting or illuminating. Most of it seems like you would easily pick up elsewhere in smaller works, or just intuitively if you're so inclined, and I didn't find the connective tissue of the book added much or even connected the ideas the way they were intended to. Not going to rate it because it's entirely possible I just should have picked this up at a different time.
