Passionate People are often viewed as being sincere. Most people believe that you can’t fake passion.
Presentation Zen has an interesting post today about this topic. Here is the money quote:
“The best presenters I have ever seen were not trained actors or professional presenters (though they may indeed present a lot). The best presentations I have seen were from everyday business people, designers, or researchers who (1) had a clear interest in their topic and about sharing it with the audience, (2) had their material down clearly and accurately in their minds and in their visuals, and (3) they displayed a clear passion for the material and made warm connections with their audience, connections that were undoubtedly sincere.”
Feeling passionately about something is a huge advantage. Your audience will be more inclined to believe you if they feel what you feel.
