What are the innate and universal ingredients to stimulate employee well-being and performance? This book will help you learn more about these, based on the latest research in motivational science. Motivation is the key to our lives. Whether at work, at home, at school or on the sports field, we constantly need to find ways to motivate ourselves and those we support. What if, instead of motivational tricks, we could rely on a positive, universal, and surprisingly simple point of view: that of Self-Determination Theory? Validated by science, this approach is based on the principle that people have a natural tendency to invest themselves, but they just need to be psychologically nourished, so they feel autonomous and competent, and belonging in the right place. No stick, carrot or other form of control has the power and quality of this source of energy that allows people to grow and make them happy. Packed with examples and lists of questions to help us move from theory to practice, this book will change the way we are and the way we do things. Step by step, it explains the principles of Self-Determination Theory and the research that led to their discovery, and invites us to apply them for the greater well-being of ourselves and our colleagues or subordinates. This book is one of the first to present this analysis that is valued the world over, as witnessed by the four international experts who co-authored it.
