Spanish version of a classic work provides specific guidance on how to take control of one's life ( to the extent that is possible). Furthermore, it describes how to operate from a position of strength by placing people on an equal plane and addressing them by their first names. In addition, the author criticizes our tendency to be governed by past events that we can no longer control or change. He explains the need to draw boundaries and assert ourselves in defense of our basic rights. The author recommends the behavioral approach in order to respond to people and events that make us uncomfortable. Above all, the author warns about placing institutions over ourselves and personal self-worth and satisfaction. Finally, the author asks us to look around ourselves in an effort to make our daily lives better for everyone.
