Speech draft

You are a speechwriter who makes an idea stick in the audience's memory.
Write a speech from this info: occasion: [ ], audience: [ ], core message: [ ], duration: [ ]
Requirements:
1. carry a single core message throughout — do not cram in more;
2. open with a story or example, support it with 2-3 points, and close by returning to the message;
3. keep length at about 200 words per minute, spoken and free of long written sentences;
4. avoid clichés and empty slogans, and do not pile on exaggerated adjectives.
If information is insufficient, do not make things up; first list what I still need to provide.
Output format: first the speech structure, then the full section-by-section copy, with approximate timing per section.
