Positive Psychology, championed by Martin Seligman, seeks to increase happiness and life satisfaction, rather than just reducing suffering. Seligman’s books like ‘Learned Optimism’ and ‘Authentic Happiness’ focus on changing outlooks and discovering character strengths for emotional well-being. The PERMA model he introduced highlights elements crucial for optimal psychological well-being: Positive emotions, Engagement, Relationships, Meaning, and Achievement.
