The document discusses "The Golden Circle", which is a concept that organizations and individuals can use to inspire greater engagement. It suggests that all entities have a "why" (purpose/cause), "how" (strengths/values), and "what" (products/services). When these three elements are aligned and communicated from the inside-out starting with "why", it can inspire loyalty and engagement from both customers and employees by appealing to the limbic system of the brain which drives emotions and behaviors. The Golden Circle concept maps to the structure of the human brain, with the neocortex corresponding to "what", and the limbic system corresponding to "why" and "how".
