What are some of the most innovative or surprising ideas presented in The Official TED Guide to Public Speaking?

The Official TED Guide to Public Speaking presents a unique approach to public speaking, challenging traditional paradigms by emphasizing the importance of a 'throughline'. This concept, borrowed from storytelling, suggests that every element of a talk should connect to a central theme or message. This can be structured in various ways, like a tree with ideas branching off the central trunk, or a loop connecting the beginning to the end. This approach challenges the conventional, often linear, methods of structuring a speech and encourages speakers to think more creatively and holistically about their presentations.

The lessons from "The Official TED Guide to Public Speaking" can be applied in today's business environment in several ways.
