Not quite as good as her first book, but well worth the read. I probably should have gotten the abridged version, because as usual I got tired of the anecdotes.
I find her types interesting — there are upholders, obligers, questioners, and rebels. Apparently most people are questioners or obligers (I think — I may be wrong about the obligers). (I’m a questioner, so for once in my life I’m not weird.) Then she classifies people in additional ways, like abstainers or moderators and so on. In fact, there seems to be some sort of classification or label in nearly every chapter!
Anyway, the information in the book is useful, and I am already using it in analyzing my own habits and improving them. Rubin’s reading voice is fairly pleasant (I listened to the Audible version), so I don’t hesitate to recommend the book.
