In this TED talk, Simon Sinek explains how great leaders inspire others to take action. He argues that it’s not enough to communicate what you do or how you do it, but that you must communicate your “why” or purpose. Sinek cites examples such as Apple, Martin Luther King Jr., and the Wright Brothers to show how successful leaders have all been able to communicate their “why” effectively. He also discusses the importance of leading with empathy and building trust with your followers.
