J have rather tendency me wary of books that deliver psy causes, recipes and tips everything to explain the why of an evil being, of a lack of self-confidence, or any other "psy problem." Our identity and our way of feeling being intimately related to our personal history, it often if not always need a dive in it to find the answers that you will never find in the express and enticing formulas too many books addressing psychological issues . C is in this spirit that I have bought this book, there are now a few years. Ny I have found neither recipe nor express solution. But jy have found many ways reflection through very simple and pedagogical pages that explain the difference between self-esteem and self-confidence, events that may impair the one or the other, the means to protect and remedy its alterations without falling into the opposite excess that would be to believe that it is always right. A book that makes you think and makes you move .. what better?
