This document summarizes key concepts from positive psychology, including resilience, flourishing, and their relationship. It discusses how resilience involves bouncing back from adversity through factors like strong values, social support, and optimism. Resilience can be taught through training programs. Flourishing goes beyond happiness to include PERMA dimensions: positive emotion, engagement, relationships, meaning and accomplishment. These dimensions are independently measurable and contribute to well-being. Flourishing involves living according to one's signature strengths and finding flow in challenging activities.
