So what? Tell your readers the HOW
Does it really matter why business speakers give poor presentations? Get to the action quickly and the why is irrelevant. Persuasion is most effective when the speaker focuses on the new way of doing things and avoids any comparison to the old way. Readers searching for better presentation skills will remember new and better presentation techniques by learning them, not by having the bad old ways rehashed again and again.Please read books with actual action steps, not theory, and you'll be a business speaker who doesn't speak like an idiot.
