When we are under excessive stress, we frequently want to "downshift" and run away from the problem. We lose motivation and engagement when we are under too little stress. What exactly happens in the middle zone, or what psychologists refer to as "positive stress," and how can we make the most of it to get beyond formidable obstacles and perform at our best? Ben Ramalingam has a unique vantage point from which to identify the key principles that can enable anyone to use stress as an opportunity for change. Ben Ramalingam is a globally recognised change-maker who has worked at organisations like the United Nations, the International Red Cross, and the World Bank. We discover how a shift in mindset enables musicians to wow massive crowds despite all obstacles and how astronauts focus on originality to overcome life-threatening incidents; and how discovering a sense of purpose allows emergency health workers and aid experts to deal with unprecedented crises.
