When it’s time to write a presentation, most people put together an outline which they immediately turn into a PowerPoint. They rehearse it once or twice to themselves, and then think they’re good to go.
Writing a powerful presentation is like writing a good article. You write, then rewrite, then rewrite some more. Professional writers rewrite their work a dozen times. Look to make it more condensed. Try to eliminate half the bullet points. Knock out the redundancies and overly glib lines. Just put the key points on the slides, not every word you’re going to say.
Be single focused. Ask yourself what is the one thing you want everyone to remember and make sure it is in the open, middle and close.
Finally, have a friend listen to you present it. Fix those parts where he or she either passes out or glazes over.
Work it, baby.
