The 1 Macronutrient High Performers Skip After 60 - Arthur Brooks, PhD | GLS #228

About this video

Dr. Arthur Brooks, a happiness researcher and behavioral scientist, discusses his framework for understanding and pursuing well-being. He defines happiness not as a feeling but as three ‘macronutrients’: enjoyment (pleasure plus people plus memory), satisfaction (the joy of accomplishment through struggle), and meaning. Brooks argues that modern culture sabotages happiness through feelings-based thinking, technology overuse that disrupts brain hemispheric balance, and the mistaken pursuit of constant pleasure rather than balanced well-being.

Key takeaways

• According to Brooks, happiness consists of three components: enjoyment (which requires making pleasure social and memorable), satisfaction (derived from struggle and accomplishment), and meaning (the most essential ‘protein’ of happiness)
• Brooks suggests a decision-making framework of seeking 80% excitement, 20% fear, and near-zero ‘deadness’ when facing major life choices, acting once you have 80% situational awareness
• Brooks claims that technology use, particularly smartphones, contributes to a meaning crisis by over-activating the left brain hemisphere while suppressing the right hemisphere responsible for meaning and transcendence; he recommends tech-free periods during the first hour of day, mealtimes, and last hour before bed
