Positive psychology aims to study what goes right in life by focusing on people's strengths and how to build the best qualities, not just repairing problems. It examines how people can lead fulfilling lives and reach their potential. Some key topics in positive psychology include mindfulness, optimism, resilience, character strengths, and well-being. While criticized for being too similar to earlier humanistic psychology and lacking a unified theory, positive psychology provides a framework for understanding human flourishing.
