Great ideas that I now understand can be derived from high school drama class. I remember this phrase specifically,
Believe that you're an interesting person.
No matter what message is being delivered, we must believe that we are interesting people. When we believe it, others will as well. Dale Carnegie teaches something similar in his book How to Win Friends and Influence People.
"I was presenting the same facts this time that I had presented previously. But this time I was using dramatization, showmanship--and what a difference it made."
