Grit, according to the thought leader and social scientist Dr. Paul G. Stoltz, is the “capacity to dig deep, to do whatever it takes” to achieve one’s goals. Understanding how to strengthen and deploy grit has been central to Stoltz’s life’s work. In 1987, he founded Peak Learning, Inc., a consultancy that has worked with leading Fortune 500 companies and government agencies. He’s also the founder and managing director of the GRIT Institute and Global Resilience Institute, a research organization. His resume is an over-achiever’s dream: collaborations with MIT, Carnegie Mellon, Harvard Business Review,Princeton, and Cornell, among others.
