In this video, motivational speaker Kevin Kelly says “Why do we need to talk about this? At the end of the day what your story is, screams at me without opening your mouth and you gotta make sure that your story is on the money. So I want to share a study that was done first at Harvard Business School. They showed students a 10 second video, and  asked students to rate the professor on 15 different criteria. 85% were able to assess the speaker based on 15 different criteria on a 10 second silent video. Investigating further, they decided to show a 5 second silent video to a different group and again ask them to assess the professor based on 15 different criteria.”  Click on video to know what happened next.
