i've been listening to the podcast version of Roy Peter Clark's "Writing Tools". first, i recommend you give the time to these short podcasts. i think you'll find that these tools will work for your public speaking and storytelling (which should describe your public speaking method).
thought I would comment a bit on the tip titled "get the name of the dog". your story comes alive when you use describe in detail the color of the rotary phone on the wall, the color, model, and year of the car, the exact weather of the moment. notice this in the next news article you read. i think you will discover journalists usually give "the name of the dog" even in a story of just a few hundred words.
so, the next time you tell a story; describe some element of the plot in some combination of brief but significant detail. see if you can win that "my story is better than your story" conversation exchange that characterizes most adult interactions.
