Scott Young, having studied the results of recent research and the experience of outstanding personalities, found those teaching methods that have the maximum effect: they allow you to better understand remember information, as well as reveal new talents. He formulated nine principles of rapid self-education, allowing you to master complex skills, gain the necessary knowledge, maximize competitive advantages and build a career. These principles will be useful to anyone who wants to learn something on their own: master a language (or several languages), get a new profession, or master several tools to create a product or business from scratch.
