Although I have read reviews of people who put three stars or less, I found this book, with its clear style, very instructive.
It meets all personal questions.
It reinforces a personal point of view.
It requires having already made a big personal work on oneself, having cleaned a number of personal problems to achieve a certain level of understanding necessary for reading this book. I find.
But I realized many of my own current difficulties.
The reading is interesting.
