What is, what could be, call-to-action

This is the story structure behind every TED talk:

  • Act I: What is
  • Act II: What could be.
  • Act III: The call to action.

You can build this story arc in different lengths for different settings: the elevator pitch, the 15 minute explanation, the 1hr story.
