For most of my life, I struggled with my vision. When I was at primary school, my big, colorful glasses, akin to Dame Edna's, were a constant source of frustration and shame. My poor eyesight, I thought, was something unchangeable, defined only by a prescription and better frames as the fashion moved on from 80s excess. But recently, I’ve discovered something mindblowing: our vision is not just about seeing clearly; it's a powerful, trainable tool that directly shapes our leadership, nervous system, and ability to perform at our peak.
