When you listen to someone present a message or an opinion, can you tell if they are repeating something they have heard from others, or if it is something they have personally lived? Which has more impact on you? There is a quality of personal engagement and involvement that cannot be duplicated by simply passing along information, even if it is true. Do you suppose the same effect works in the things that you present, that it is obvious whether it is second-hand information or firsthand experience? What things do you have sufficient firsthand experience of to make a convincing presentation?
