If you don't already know, let me explain. The presentation is not your deck. If you want your presentation to sing then it's important to remember to frame your presentation. Here it is:
1. Hook them
2. State your objectives
3. Explain how it's relevant
4. Set expectations
You don't need four sentences or stories here. One good story can do 1 and 3 and then two sentences after can cover items 2 and 4.
You get the idea. Then launch into what you came to say.
