Here is a link to the website by a speaker who writes about how to structure a narrative example for a speech. I also include a portion of the letter from my student in Singapore, Zed Ngoh, who sent me the link. I have embedded the link in the text of my student’s comments. I also attach a pdf of notes about the structure as mentioned below in Zed’s letter. Zed’s drawing

Hope this helps you in your efforts to support your speeches with personal examples.
