In his influential book, 'Start with Why,' Simon Sinek explores what makes great leaders and organizations truly exceptional. He introduces 'The Golden Circle,' a powerful model that illustrates how legendary leaders think, act, and communicate. Sinek argues that they all start with 'Why'—their core purpose or belief—before addressing 'How' they do it or 'What' they do. This inside-out approach inspires people on a deeper, emotional level, fostering passionate loyalty and creating movements. The book provides a clear framework for building businesses, leading movements, and inspiring people.
