Simon Sinek's iconic global bestseller has sold more than three million copies by asking a simple fundamental question: Why are some people and organisations more innovative, more influential, and more profitable than others? The answer to why is another why. Leaders like Martin Luther King Jr., Steve Jobs, and the Wright Brothers had little in common, but they all started with a WHY. They realized that people won't truly buy into an idea, a movement, a product or a service until they understand the WHY behind it. With a new foreword, and updates throughout ? like the importance of holding onto our WHY in a social media obsessed world - this 15th anniversary edition celebrates the simple but transformative idea that leads people to inspire greatness.
