I think you may have taken it all a bit seriously rather than just taking the message.
I chose to let go of any personal examination, analysing or judgement of the wording of this book as I started it, realising that perhaps it didn't matter and that I would not know the outcome of doing this book unless I did it, so did it anyway, finished the entire course, and it ended up moving me forward in life hugely, in a very concrete and hands-on way.
The power of this book is especially in the exercises given. This book is very practical this way, and is very much a course to be DONE, and to be experienced, over just being read.
I am convinced that if you would have done the exercises, you would have gained exactly that what you were looking for:
your ideas organised and a rejuvenated passion for writing.
Not only that, I am sure you probably would have picked up your writing before even finishing this book. This is what this book did for me.
My advice would be: don't judge it, just do it, and you will be surprised by how effective this is.
