Which first-grader will graduate from school with a gold medal? Which young violinist will become an outstanding musician? Which of the hired sales managers will close multi-million dollar deals? Angela Duckworth believes she can answer these questions with almost 100% accuracy. She argues that a person's success has little to do with talent and innate abilities. Real achievements are determined by completely different qualities. And the most important of them is PERSISTENCE. In the book, Darkvot tells how to develop this quality to the maximum and find your calling. It also offers a questionnaire that allows you to determine your level of perseverance and compare it with the level of the average American.
