Be passionate about your communications. Watching Oprah Winfrey, you get the sense that she cares very deeply about what she does. As a communicator on television and in her publication, Oprah finds lessons that she believes will help viewers and readers live more satisfied lives. Jack Welch was passionate about his companies, and in particular about the people in them. Passion is evident in the prose of Peter Drucker, who has been preaching insights into management for more than seven decades.
People need to see that you care about what you are doing and what you are communicating. You communicate passion through both the intensity of your delivery and the consistency of your effort. When people see you delivering a message over and over again, and doing it convincingly, they will get the idea that what you are saying is important and they'd better pay attention.
