What's the best way to start a story? just dive right in. Don't say let me tell you a story. Don't tell me out today I want to talk about Baba. Just happy. You don't have to say thank you Good morning.
Any of that just hop right in to the store. Establish the setting. That is the best way for many reasons. It's not how most speakers start, although the good ones do. And it's devoid of all the throat clearing cliches most people use when they start a presentation.
