The Opposite is True is a work of art.”

“If Teddy Roosevelt, Winston Churchill, H.L. Mencken, and Jordan Peterson successfully graduated the FBI Academy and spent a decade as a hard-working Special Agent, this is the masterful book they could have collectively co-written. That co-authorship foursome will not, of course, ever materialize. Instead however, it is Efren A. Delgado who so magnificently penned The Opposite Is True, and it is no less of a page-turner than if any one or a combination of the aforementioned literary luminaries had written it. Capturing history, society, culture, psychology, media, the criminal justice system, and much more, all under the sometimes wary and skeptical eye of a brilliant FBI special agent in the early 21st Century, this is a must read for those wishing to understand the turbulent times in which we presently live. If there is a means to survive this present maelstrom of conflicting and ever-shifting national and international paradigms within the coming decades, the answers may just lie in this book. Delgado certainly poses the relevant questions and, quite frankly, answers most of them.
This is a grand slam of a first book for Delgado. I’m anxiously awaiting the sequel.

This is an important book, a commonsense—and previously unexpored—means of becoming your best self while meeting others half way and forging common ground. By exploring the axis of empathy, humility, and wisdom, it presents practical strategies for delimiting your personal horizons, strategies that are employed to our benefit or ignored at our peril.

The Opposite is True 3D cover

Reading The Opposite is True by Efren Delgado was an eye-opening and transformative experience. As someone who has always been hard on themselves for their imperfections, this book offered a refreshing perspective on how to embrace and harness these so-called flaws. Delgado, with his extensive background in the FBI and psychology, brings a unique and authoritative voice to the topic. It’s not just a book; it’s a practical guide to transforming life’s challenges into opportunities for growth and success. I highly recommend it to anyone seeking clarity and actionable wisdom in their personal and professional lives. The Opposite is True is a masterclass in understanding and leveraging the paradoxical truths of our existence for genuine success. Plus, if you have the chance, search for Efren on podcasts because he is a wonderful and articulate guest as well!

Wow, Efren, I feel like I just took a graduate course in everthing I never learned in school!

Efren’s open vulnerability expands beyond the academic world and invites you to participate in his gritty experiences. His depictions of other notable lives offer applicable demonstrations of how and why we should all live more deliberately. He does not hold anything back. And every theory he offers, including “The Opposite is True,” is corroborated by his own visceral admissions and unexpected exchanges with deviants, their victims, or by his use of history, allegory, and scientific principles to take you on a spiritual journey to motivating, yet practical, enlightenment.

The Opposite is True, yes. But this is but one of many paradoxes he exposes throughout his text that will leave you reflecting on your past, digesting your “Now,” and contemplating the gaping wide door of your unique future.
