Fellow speaker,
You don't begin with a "full blown" story at first. First you get ideas that you work over in our head. Then, after awhile, put down notes about what might work. Next, work over the notes, and finally go out and speak the story to an audience. After the speech is over you review the audience's reaction to the story, seeing what worked and what didn't work in your story, so you can make the story better for your next speech.
Redoing,
Tim
