Brian Johnson presents a 10-minute Philosopher's Notes TV episode summarizing Sonja Lyubomirsky's The How of Happiness. He explains the paper's central empirical claim — roughly 50% of happiness is genetic, ~10% is life circumstances, and ~40% is behavioral (the "40% solution") — and reviews 12 evidence-based happiness activities (e.g., gratitude, optimism, acts of kindness, exercise, goal-setting). Johnson emphasizes practice, choosing activities that inspire you, and cites specific practical examples (daily gratitude log, exercise as effective as Zoloft, best-possible selves diary).
