I picked up this book after two friends told me (enthusiastically) about it. Like many people I occasionally find myself struggling with indicating boundaries, particularly in the work-field, so I figured, why not. I have to admit though that after finishing the book, it has left me feeling kind of 'meh' about it. Although, in fairness, a lot of that will have to do with the fact I really didn't feel like the target group for this book (although demographically speaking, I certainly am). On top of that, while I struggle with boundaries somewhat, this book is really aimed at those who have literally no boundaries at all and are basically living doormats. For those who really struggle so hard, this book might be a good fit.
What I liked
The book is written in an engaging, direct style that is easy to follow. Some parts and examples have a nice self-deprecating flair to it. On top of that, the book offers various exercises one can do to improve boundaries. Although Elman doesn't explain them in any detail, she hints at/uses a number of models common in other self-help books (Eisenhower's importance/urgency matrix, stimulus-response and shifting paradigms)
The part of the book I enjoyed the most was where the author listed simple replies to comments clearly meant to manipulate, guilt-trip or otherwise derail attempts at boundary-setting. I've copied down a couple for future use. I would say I look forward to giving them a whirl, but that would be equal to saying I look forward to someone crossing my boundaries.
The book has a very blunt and direct style, and doesn't focus much on empathy or conversation. However, in a way that might be a good thing, because someone who is prone to having their boundaries pushed will likely go too much for those elements already, and a good dose of harshness might be just what is needed.
What I didn't like
The book is very heavily targeted towards a niche demographic: women in their twenties, who are either in college or entrepreneurs, and care strongly about social issues. I expect this is because this is also the demographic the author herself belongs to, and she uses primarily personal examples in her book. In essence, there's nothing wrong with a book aimed at a niche, but I would have appreciated it if had been made more clear to me from the book's cover/title/blurb. Although I should take some of the blame, as one glance at the author's Instagram page could have shown me this (and then I likely wouldn't have picked it up).
Something I've seen with many self-help books (and it crops up here as well) is that often the examples just aren't that....lifelike. They'll either portray a situation where someone's behaviour is so outrageous that a child could see it's not okay, or some details have been left out which just make the examples look like weird 'and then everyone clapped' type stories.
The author uses the concept of 'childhood trauma' a little too liberally for my tastes. Any and all issues with boundaries she, without hesitation, attributes to some parenting failure you had to endure as a child.
Finally, the book has very strong undertones of identity activism. To me this is a negative because while I am sympathetic to many of their causes, I am often not a fan of their methods and their rhetoric. I appreciate that this is a personal dislike though. If you're into identity activism this book will not disappoint. The book veers off into women-specific issues regularly, and other 'staples' such as gaslighting exes, fat-shaming friends and patriarchal white men all get their time in the sun.
