Public Speaking is a Performance Art

I had a thought pop in my head recently about public speaking. When you are giving a speech or presentation you have to become someone else. You have to give a performance. No one acts the same in general conservation and when they give a presentation. There is a difference! You have to be genuine and likeable. But you can’t be the same person you are when having a beer with your friends. You may have to project that people would have beer with you.
