In 1956, George A. Miller revolutionized our understanding of the human mind with his groundbreaking paper, "The Magical Number Seven, Plus or Minus Two," which revealed that the average person can hold about 7 (±2) items in their short-term memory. This elegant insight became a cornerstone of cognitive psychology, shifting the field from behaviourism toward a deeper appreciation of internal mental processes. Miller’s work not only laid the foundation for understanding memory and information processing but also underscored the limits of human attention, a concept with profound implications for personal wellbeing and societal health. By recognising our cognitive limits, we can design more humane technologies, streamline communication, reduce mental overload, and foster environments, whether in schools, workplaces, or healthcare, that support clarity, focus, and resilience. Miller's legacy reminds us that by respecting the architecture of the mind, we can build a more compassionate and cognitively sustainable world. The motivation to build such a world derives from noble core values held by deeply principled people. The energy and vision for such a world comes from God, the benevolent Creator and Sustainer of all things.
