At the tender ages of seven and five, my sister and I discovered what would later be known as positive psychology. During a game that went awry, I convinced my injured sister that she was a unicorn, which stopped her tears and made her happy. This incident was a precursor to a scientific revolution in understanding the human brain.

In the span of two million years, the human brain has nearly tripled in mass. A key factor in this growth is the development of the frontal lobe, particularly the prefrontal cortex. This part of the brain acts as an experience simulator, allowing humans to contemplate actions by mentally simulating them before they happen, a unique adaptation that other animals lack.
