The 10/20/30 Rule of PowerPoint That I Wish Everyone Followed
Guy Kawasaki writes, "A PowerPoint presentation should have ten slides, last no more than twenty minutes, and contain no font smaller than thirty points" (The 10/20/30 Rule of Powerpoint). I wish everyone who prepares a presentation would follow this advice. Long PowerPoints disrupt any kind of narrative flow and dynamic energy that can build up when you deliver your message.
