Look first to Personal Experience. Its the human story that entrances the human audience.
Recall moments in your life that were turning points, discoveries, high on adventure or emotions.
Draw the scene out in as much detail as you can. Be VIVID and explore the environment: talk about the temperature, the scenery, the behaviours in the background, the tension or joy, the characters
Add some dialogue. Who was there? Who said what? You can use different voices if that works for you.
And to wrap up the speech add your personal reflection on what you learnt.
