Lesson 2: What's the Big Idea?

What is the Big Idea?

In this video, Mike explores how every great TEDx talk is built around a “Big Idea”—a clear, compelling thread that ties the talk together and captures its soul. Drawing on insights from TED and poetry by William Stafford, the presentation explains that a Big Idea should be simple, universal, and inspiring—something you can state in one sentence, that sparks curiosity and connects personal stories to bigger truths. Viewers will learn practical strategies for identifying and refining their own Big Idea, whether they’re a coach or a speaker, and discover the questions that lead to talks with lasting impact.
