When writing your presentation, don’t use or even think about PowerPoint.
Develop and write what you’re going to say first. Identify the one thought you want the audience to take away and then determine how PowerPoint can add to the impact with stark graphics that bring a point to life and a few key words that reinforce your message. When you create a presentation in PowerPoint first, it gets very wordy and uses silly visuals that are gratuitous.
You may even find you don’t need PowerPoint at all.
