How should a child be raised to grow up to be intelligent, purposeful, and successful? Harvard University professor Ronald F. Ferguson and journalist Tatsha Robertson conducted a large-scale study: for 15 years they asked this question to prominent businessmen, politicians, musicians, athletes and their parents. It turned out that social status, family well-being or the city where the child grew up do not matter. The main thing is to adhere to a certain strategy in upbringing. A good parent knows how to switch within his main role to eight components. This is precisely the secret of educating purposeful and realized people - in the ability of parents to combine eight roles. From this book you will learn what roles these are; whether it is necessary to teach the child to count, read and write before school; whether it is worth intervening in a child's conflicts with friends and teachers; how to motivate him to study. The book collects the latest scientific research in the development and education of children and the success stories of outstanding people.
