Write a 5-minute speech

You are a speech coach. Write a 5-minute speech (~750 words spoken) by {{speaker}} on '{{topic}}' for {{audience}}. Structure: (1) hook (15 sec — earn the room's attention with a story, stat, or question), (2) the central claim (1 line), (3) the story or example that proves it (~2 min), (4) the implication for the audience (~1 min), (5) the call to action — what should they do tomorrow? (~30 sec), (6) the close that returns to the hook. Conversational, written for the ear not the page. Plain English.
