Simon Sinek is a bestselling author and visionary speaker, best known for introducing the importance of 'Why' and inspiring leaders worldwide through his books, talks, and groundbreaking ideas on optimism and leadership.
Who is Simon Sinek?
Simon Sinek is the influential thinker behind the concept of ‘The Golden Circle’, which he explores in further detail in his books “Start With Why” and “The Infinite Game”. As the founder of The Optimism Company and The Curve, he has inspired leaders across industries, governments, and even the U.S. Armed Forces. He is ranked in Thinkers50 and was named the world’s top motivational speaker in 2021, with his TED Talk, “How Great Leaders Inspire Action”, being the second most-watched of all time.
What is 'The Golden Circle'?
The ‘Golden Circle’ is a model for inspiring leadership and communication built around three layers: Why, How, and What. At the centre is the 'why,' the core purpose, belief, or cause that drives an organisation. The ‘how’ explains the unique methods or values that bring that purpose to life. The outer circle is the ‘what’, the tangible products, services, or results. Simon's message is that the best leaders and organisations start with ‘why’, then show ‘how’, and finally share ‘what’, creating a message that inspires trust, loyalty, and action.
Who Helps Bring Simon's Ideology to Life?
Through Simon’s infectious messaging and commitment to helping leaders find their purpose, these speakers support Simon’s concept in their own work:
