How important is image? Obviously film stars have to look right for the part, but what about other people in the public eye? For example, do politicians have to think about their appearance, too? Albert Mehrabian studied the effect that speakers have on their audience. His research showed that only 7% of the effect depends on what you say; 38% of the effect comes from your voice; but a huge 55% of the effect comes from your appearance. So you don’t have to worry too much about content. Your voice and your appearance are much more important.
