In an age where AI can master in months what humans learn in decades, why are we still trapped in four-year degrees and annual performance reviews? The most successful people have already abandoned these obsolete timelines for something radically different: regenerative learning cycles that transform them every six months. Russell John Cailey calls this the Firefly Effect-the ability to generate your own light in a world of broken systems. From guerrilla gardeners in South LA to Starbucks managers inventing billion-dollar products, from students escaping standardized testing to executives reinventing entire industries, this book reveals how fireflies are rising everywhere. Learn the six-month transformation framework, discover why wonder beats knowledge, and join a movement of people who refuse to wait for permission to shine. Because when systems break, fireflies rise.
