1. Think of your audience. If you have just 5 minutes to prepare, chances are you’re in the room with them already. Look around.
2. Decide what you want to tell them.
3. Add 3 stories relevant to your audience and to what you want to tell them. You’ll have about 90 seconds for each of them.
4. For each story, add what it means to the audience in the context of what you want to tell them.
5. Add a call to action to the end.
6. Add an opening statement (yes, this does belong to the end).
7. Time’s up. Go give the speech!

The quality of your speech will depend mainly on the following two factors:

a) The relevance of your stories and

b) How well you’ll be able to tell them

To improve a): Collect your stories. Keep adding to your storybook.

To improve b): Refine your stories. Keep telling them, improving them and telling them again.

There’s a lot of preparation behind impromptu speaking.
