Michael Bungay Stanier's book "The Coaching Habit: Say Less, Ask More - Change the Way You Lead Forever." The book focuses on the power of asking questions to help others solve their own problems and develop their potential. It outlines seven essential questions to help build a coaching habit, which Stanier argues is crucial for working less hard and having more impact. The book also includes practical tips and strategies for changing behaviors, as well as insights from neuroscience and behavioral economics to back up the effectiveness of asking the right questions.
