Our emotions affect our well-being, relationships, and self-realization. Mostly it is the misunderstanding of the nature of our own feelings, shame for excessive emotionality or, on the contrary, stiffness that prevents us from becoming happy. Over 25 years of work, Mark Brackett has developed a surprisingly effective system for improving the lives of children and adults LEADER, which is that emotions can be learned to use, and then they will help, not hinder our well-being. This system is used in thousands of schools. It has been proven that it reduces stress and burnout, improves the school climate, and improves academic performance. In this book, Brackett shares his proven strategy with readers.
