You should watch and analyze great talks to understand their flow and structure. Start by identifying what message you want to convey to the audience, then plan a research-driven talk outline that groups topics together based on connections and relevance. Create an excitement curve in your talk to keep the audience engaged throughout, starting with something exciting, followed by a drop in energy, and ending with a high note. The first 5 minutes of your talk are crucial for capturing the audience's attention, so start with a story or intro that resonates with them and addresses their pain points. When telling stories, use time and place references to make them more relatable, be emotional to show your feelings, and use this ancient technique to teach new knowledge. Finally, end your talk on a high note by summarizing the key message and leaving the audience with thoughts on how they can apply it.
