The document discusses building resilience to handle stress and adversity. It notes that current approaches focus on short-term problem solving and are becoming commoditized. A new approach called mental fitness is proposed, focusing on using internal resources to strengthen neural connections, build emotional intelligence, and measure functional capacity rather than diagnosis. Developing resilience requires addressing brain basics, personal effectiveness, emotional intelligence, and interpersonal competence. Cultural change within organizations can promote mental fitness through creating awareness, education, skills training, and leadership that leads by example.
