People love stories, McDonald said, so tell them a story. It also makes it easier for others to remember you later on.
Self-improvement guru Dale Carnegie said in his book, "Public Speaking and Influencing Men in Business", that our minds are essentially "associate machines", which means we remember things better when there's a story or association attached to the subject. In other words, if you want people to remember you, tell them a story and make sure it's good.
