Communication is the same integral human need as any other basic need. The art of building connections with people is the most important quality of a person and the key to his prosperity in society. Therefore, it is so necessary to have social interaction skills. In this book you will find data on research and discoveries in the field of human behavior. Theoretical considerations are supported by practical recommendations for achieving any social goals. You will receive answers to the questions: how to achieve popularity and win the sympathy of others; how much the psychology of a positive attitude matters, how two-way perception and mutuality of sympathy affect your relationships. You will become aware of the toxic habits you have that need to be eliminated if you strive for social success, and you will learn how to make a favorable impression. Social intelligence - and this is what it is all about - is an invisible force that will support you and allow you to increase your social status.
