Story telling: By sharing a story in a public story you are using a hook. A hook is something that grabs your audience’s attention and makes them sit up and listen. Share an experience you have at first or ask questions because this is a feeling of dynamicity and people like to be active. You will find that these people are just like you by giving them something they can identify with. Just be sure that your story has first of all a point, then a beginning and an end because it is terrible to tell a story to a "hooked" audience and to forget the point.
