Learn the science of well-being — positive psychology the way it is actually studied. Master the major theories and the researchers behind them: Seligman’s PERMA model of flourishing, Csikszentmihalyi’s flow, Fredrickson’s broaden-and-build theory of positive emotion, Dweck’s growth vs fixed mindset, Duckworth’s grit, Deci and Ryan’s self-determination theory (autonomy, competence, relatedness), and the VIA character strengths. Understand what the evidence says about happiness — hedonic adaptation and the set point, why money’s effect on well-being plateaus, and which interventions actually help (gratitude, savoring, acts of kindness, using your strengths). Every question is grounded in peer-reviewed research and names the common myths — that happiness is purely genetic, that chasing pleasure is the path to it, that willpower is fixed. Distinct from Mindfulness (attention training) and Emotional Intelligence (reading feelings): this is the research on what makes life go well. Educational only — the science of flourishing, not therapy, treatment, or clinical advice.
