Infallible, sure of ourselves, able to better manage our emotions, appreciated and admired by others and completely satisfied with our life. These are the new standards ―amplified by social networks― that we are called to adhere to today in order to truly feel up to it. These models are at the origin of a true "epidemic of insecurity" that affects all the fundamental relationships of our existence: the one with ourselves, the one with others and the one with the surrounding world. This book also offers a series of fundamental recommendations collected after a single essential postulate: "Self-esteem is not inherited, it is built."
