The main goal of this volume is to analyse human training to achievement contexts. Using examples of developmental and high performance contexts, topics related to talent development, athletes and teams' training for high performance situations, and leaders' training to maximum professional efficacy (including mainly the cases of sports coaches) are discussed. How to coach individuals, teams, and leaders to high performance is addressed by numerous authors. This is a journey through the complexity of human functioning being assumed in this book; it is a broad and deep perspective of the factors involved in human adaptation, human development, and human training. In summary, this book addresses the fundamental challenge referred to by Kennon M Sheldon in the Preface of this book, namely, how to make things go right in our lives.
