Discover what keeps you stuck—and prepare for a miraculous breakthrough. What if self-improvement is a booby-trap? And what if there is actually a way to change one’s life—in all areas, all at once—by finding and shifting the one hidden issue that has been creating all of the stuckness all along? Coming out of an abusive childhood and then living with the outcomes of that ongoing pain, Brian D. Ridgway invested over $300,000 and tens of thousands of hours over thirty-plus years on self-help, personal development, and business/money/success courses—as his life got worse and worse. Finding himself in desperate circumstances, suicidal and stuck, he experienced an awakening that took him from homeless to living the dream in Hawaii in less than ninety days. In that awakening, he was given the Level 5 Paradigm. Since that “miracle moment,” he has been able to help people around the world to take their first steps into true freedom—and in this book, he tells his story.
