A fascinating read. I did not know much about Jordan Peterson before reading this book, I only saw that there were some controversial statements about how he has come across. It is insightful, whether you agree with what he is writing or not.

I'm sorry, but I did not finish reading the book. 

I requested '12 Rules' out of curiosity: Peterson was in the news, and I had listened to an entertaining discussion on YouTube between Peterson and Camille Paglia. '12 Rules', however, was rambling and pretentious. I couldn't bring myself to read on seriously after the first couple of sections, so only skimmed the remainder. 

Obviously not a fair or full critique, but I don't think serious 'life advice' is actually Peterson's metier.

I thought this would be a great self-help book but it turned out to be something a little different, and unfortunately me and the writer don't see eye-to-eye on some topics.

Although Jordan Peterson is a well known speaker, I'm afraid to say he isn't a great writer. I struggled to read this book, it read like thoughts in his mind which doesn't really have any structure. The thoughts are interesting, but they are probably better in lecture format than book format.

I just couldn't bring myself to agree with anything this man said. I'm sad by how many people seem to find value in substance in this book given that there Peterson is so clearly writing from a nefarious agenda. I'm not surprised he's become such a darling of the alt-right -- it's entirely by design.

A fantastic book that I will recommend to every person I know. It gives the reader hope and makes them think about every little thing that surrounds us.

If this could be any more abhorrent I’d be surprised.  A bible and a manual for a new generation of toxic masculinity, which has set back the cause of equality fifty years.  Avoid like the plague it is.

And after finishing this book, I can reveal Jordan Peterson’s core message in three words—take personal responsibility. 
 
This book has sold zillions of copies.  There obviously is a need for self-help manuals and this one is engagingly confessional and full of homely examples and snappy illustrations.

These nuggets of grandfatherly wisdom are spread over 448 pages. As others have mentioned, the book is divided into chapters with each title representing a specific rule for life explained in an essay.  There is good advice here for troubled, lost people.
 
However, his prose is clunky and I found the book a difficult slog. Some of his contentions are risible to me such as his idea that male alienation is due to the feminisation of society.  And he makes fun of cat owners!  I think this book is best appreciated by young men who are bewildered by the strange new social forces.

I'm sorry, I tried to read this book, but the writing style did not gel with me at all and I had to abandon it

I agree with a lot of Jordan Peterson's ideas about struggle and hard work and biology, but he is such a hard writer to read! Too dense, he's just not a very good writer I could get along with at all.

Forget the headlines, misrepresentations, hatchet jobs and all the other nonsense you think you know about Jordan Peterson and read his book, the mans words himself. I don't agree with everything he says, his Christian analogy seems a bit stretched at times but he's just working from what he knows. Knowledgable and full of common sense, this book is like a breath of fresh air in a world obsessed with narcisism and outrage culture.

I really wanted to enjoy this book and find value from it but instead I found it hard going. The very idea of 12 rules is, to me, about simplicity and core values. While I found the book was an attempt at the latter I definitely found the former lacking as the writing style meandered and at points I found myself trying to recall exactly what point was originally being made.

Really interesting. I keep referring back to it as it completely challenges the readers way of thinking

Oh, give me strength! – was my main reaction to this preachy, condescending, poorly written, self-opinionated, endlessly repetitive and tedious rant.  Having been seduced by the baffling welter of positive reviews I expected something rather more profound than a platitudinous ‘to-do’ list for the seemingly infantile audience the author obviously assumes.  

But I could have lived with the list had its components been justified in a concise, engaging and far more readable way.  Life is far too short to be wasted on smug, trite hogwash like this!  Incredible to think that someone who has had, at least, some exposure to scientific thinking, can produce such drivel.

Disappointed. I was really looking forward to reading this; the write up really drew me to this book. Unfortunatley it was very hard to read. I couldn't finish this book.

This is an absolutely wonderful book which I hugely enjoyed reading this bank holiday weekend. Will it change my life? I’m not quite sure yet...but watch this space.

Whilst I liked the concept of the book and did take something away from it I found it incredibly hard to read and had to "power through it"
I seriously question if someone of faith other than Christian or even no faith at all would finish reading the book because of constantly referencing stories in the Bible.  
I thought that each chapter had a great title and ending with a positive uplifting message that I felt I should hold onto BUT the filling in-between was unnecessary, convoluted  and sometimes I wondered if I should continue to read the occasional woman and less educated bashing.
I would recommend that if anyone is looking to productively change their prospective on life then they should give this book a go.  I jotted down headings and subtitles to help me take something positive away from this book.

I found this book profound, compelling, challenging and, at the same time, irreverent, funny and too often referencing God, in a variety of guises. Those times seemed to vary between what I guess was the author's personal beliefs and a sense of historical benchmarking. 

However, I loved the notions of Being and Non-Being; of the depth of explanation offered for them, though this is not an easy read and the sudden revelation that some of the rules provided when adequately explained. Some I found apparent, some amusing, and others confusing, but all was good in the end.

If you wish to challenge your thinking, this is a book to read!

So many words. An unbelieveable amount of words, to say some very simple things. Also I have no clue what lobster love lives prove about human love lives.

Make order out of chaos by sorting your own life Out First. Simply one of the greatest minds of our generation imparting his wisdom to benefit us all. Excellent book and highly recommend it.
