QUOTE : Ambiguous tasks are a good place to observe how personality traits bubble to the surface. Although few of us are elite soldiers, we’ve all experienced the kind of psychological distress these trainees encounter on their training run: managing unclear expectations, struggling with self-motivation, and balancing the use of social support with private reflection. These issues are endemic not only to the workplace, but also to relationships, health, and every aspect of life in which we seek to thrive and succeed. Not surprisingly, the leading predictor of success in elite military training programs is the same quality that distinguishes those best equipped to resolve marital conflict, to achieve favorable deal terms in business negotiations, and to bestow the gifts of good parenting on their children: the ability to tolerate psychological discomfort.
