Have you ever wanted to get rid of the negative traits of your personality? For example, to become more tolerant of others or to reduce the level of anxiety? Become more disciplined, self-confident? It is believed that people rarely change: the introvert will never break out of his shell, the narcissist will forever remain trapped in his superiority. In this book, neuroscientist, psychologist, and journalist Christian Jarrett draws on the latest scientific research to explain how we can consciously shape our personalities to influence the course of our lives. The author invites readers to assess the properties of their personality using the Big Five and Dark Triad tests, introduces them to the methods and techniques of its purposeful change and gives practical recommendations to those who are aimed at continuous self-improvement. The book is written in such a way as to help the reader begin to change directly in the process of reading, taking tests, doing interactive tasks, tracking the path traveled, and noting successes and failures.
