As the golden rule for preparing a presentation, “practice, practice, and practice” is an essential skill to everybody. And I agree that the more I practice, the better I get, because it’s never an easy job to demonstrate and explain something in front of different audience. Making a presentation involves public speaking, which can be seriously scary. Famously, speaking in public has been voted scarier than dying (which says something about its lack of popularity). So if we make enough practices before, the confidence and courage is fearless.
Since we know the importance of practice, we should know more about our audience. I usually ask myself some questions in hehearsing, such as what’s the instant reaction from audience to my words. It’s easy to do a piece of research of those potential audience. Once I know some information about them, like genders, ages, or interests, I may add the considerations into my practice.
Practice is an essential, not a rule on presentation skills. Knowing a little about audience is the tip of such a game in which audience and me are players. Then no scary anymore. Like what’s quoted in the book The Art of War on 6 century BC: “If you know others and know yourself, you will not be imperiled in a hundred battles“.
