I really tried to like this book but I just could not get in to it. Perhaps I am not the correct audience for the book, I am generally quite positive and am very happy with my life and I think I moan a normal amount, although I would be happy to change that and not moan at all, ever. I think the book may be aimed at people who really struggle to be positive or have severe issues such as not being able to leave home or major social anxiety.
I understand the idea of positive acceptance. I did find it extremely irritating that the author invented a new work "pacceptance" and used it in every other sentence. I found that very hard to paccept.
The book was filled with case studies where in most cases it was blatantly obvious what the person needed to do in order to improve their life/situation. Also with large print and generously spaced, I felt this really was a single chapter worth of information expanded to fill an entire book.
There were no references I saw to Stoicism, a subject I am very interested in that also has some very similar principles. I'm not sure how you fill a whole book on Stoicism, accepting things as they are, accepting what has happened and what will happen, while continuing to take responsibility for your actions to ensure that you give yourself the greatest chance of getting the outcome that you want. I am however, not an author or a writer and it is not my area of expertise to take a concept and expand it to fill an entire book while keeping the reader entertained, but some people do have that skill.
I think the book could be useful if you are really struggling to get through life but if you consider yourself to be in the top 10% or above (attitude wise) then I expect this will be too basic for you.
