What if the moments that shaped you
are also the map to who you can become?
We rarely stop to look back honestly at the experiences that formed us. Defined By Moments creates that space — warmly, thoughtfully, and grounded in research and mind science.
The Book
Personal story, reflection,
and mind science — together.
Defined By Moments is not a self-help book in the conventional sense.
It is an invitation — to slow down, look back honestly, and understand how the experiences that shaped you are still shaping you now.
Through personal story, guided reflection, and accessible mind science, Ron Bonnstetter offers a new way to understand the relationship between your past and your future self.

What readers are saying
"I was initially drawn to Defined by Moments because of my respect for this author's work—particularly his research on Response Process Validation Protocol and neurophenomenological gamma asymmetry. His scientific contributions have shaped how I think about brain function and clinical application, so I was curious to see how that same mind would translate experience into story. What I found was something much more personal and unexpectedly grounding. What makes this book especially meaningful to me is the way he embodies the role of teacher—not as an authority, but as a co-learner. His curiosity never plateaued. Even as he nears retirement, there is a sense of ongoing inquiry, of continued openness to discovery, which I find both rare and inspiring. Having attended his workshop at an ISNR conference, I had already been struck by the depth and implications of his work. This book adds a new dimension—it reveals the person behind the research. The scientist becomes human, reflective, and deeply aware of the journey that shaped his contributions. This is not just a story about a career. It's a story about becoming—about paying attention to the moments that quietly define us, long before we recognize their significance. I would recommend this book to anyone who values thoughtful reflection, lifelong learning, and the integration of science with lived experience. It is a beautiful, sincere account of a life shaped by curiosity, humility, and purpose."

"My home town - I grew up in the same small town as this author. His memories of life, school and growing up, helped my thoughts come alive. If you grew up in the 50's, 60's or 70's, you will feel at home in this book. We learned lessons that we had no clue would guide us for the rest of our lives. The hard parts taught us the most. So please enjoy this read that takes you from childhood dreams to real life events."

"The power of transparency and redefining the meaning behind our memories - Defined by Moments really moved me. What I appreciate most is the powerful transparency. Ron shares his life in a way that is honest, unfiltered, and deeply human. You can feel that he is not trying to impress anyone. He is simply telling the truth about the moments that shaped him. As I read, I kept thinking about how important it is to look back at our own lives. Not just at what happened, but at the meaning we assigned to those experiences at the time. And then, with maturity and self awareness, to revisit those same moments and ask, What else was there? What was I learning? How did that refine me? Dr. Bonnstetter weaves story and insight together beautifully. It feels natural, not forced. Heartfelt. Sometimes tender. Sometimes surprising. Always real. I especially loved the brain scans at the end. They reinforce something so important: our subconscious patterns are quietly guiding so many of our decisions. When we change the way we think about our experiences, we truly can change our minds and, in many ways, our reality. This is a book about reflection. About growth. About having the courage to examine your own story and find deeper meaning in it. I am grateful Ron wrote it and I hope you find as much insight and joy as I found reading it too!"
