Now that you've identified the one thing you want your audience to do after watching you and your PowerPoint presentation, you need to brainstorm every possible message Fact number that you think will motivate your audience into doing what you want. If you want them to invest in you, they're not going to invest for 189 reasons they may remember one big one or two or three, or maybe at most a handful. My recommendation, brainstorm on every possible message point, then narrow it down to just your top five. Do this before you've made your first PowerPoint slide. You can do this on a simple piece of paper or blank computer screen.
