Many people on their path in life come to the realization that there is a certain stop in personal growth, and it is time to start engaging in self-development. Self-development is constant work on oneself, self-improvement and the development of personal qualities. In this process, a person concentrates on his own desires and goals and constantly gains more and more new knowledge to achieve them. This process is fundamental to achieving success in life. If you are not confident in yourself, you constantly get kicks out of life and fill up cones, while not getting the slightest pleasure from life, there is only one way out of this situation, and that is self-development. And it is right to start such a responsible process by studying the foundations and experience of outstanding people who have achieved heights in self-improvement and, as a result, in life. The collection Bible of Self-Development includes truly fundamental classical works, which are quite simple, accessible, and at the same time describe in detail and deeply how to think and act in order to become successful and happy in our world: James Allen.
