Michelle Gielan is founder of the Institute for Applied Positive Research and an executive producer of The Happiness Advantage with Shawn Achor on PBS. She conducted a study with researchers Dr. Martin Seligman, Dr. Margaret Kern, and Lizbeth Benson from the University of Pennsylvania which found that it takes just minutes to alter one’s mood from neutral to negative simply with news reports. In this optimistic work, Gielan shows that we are all broadcasters able to influence the emotions of others through the things we talk about. Our vision of reality can do the most good when it is presented through the lens of positivity. The author presents seven keys to being a positive transformational broadcaster.

For example, when you are asked how you are doing, "scan your world for something positive, and then share it." Four kinds of questions can help you change the frequency to positive territory and promote positive change: digging for gold, shifting the focus, next best, and what else. As we amplify our role as positive broadcasters, we boost the status of others and make them look good.

Research show that 31 percent of employees are positive but aren’t expressive. They are "hidden broadcasters." If they read this book, that will no longer be the case.
