TED speaker and speaking expert Nancy Duarte suggests different presentations require different approaches:
- Requests for financial support - Tell your interesting story about your idea in 10 minutes or less - use any leftover time for questions and answers - think of the likely questions and prepare clear answers for them
- Keynote - Tell your interesting, emotional story with a clear point
