About Defined By Moments
A book about the moments that shape us, the stories we carry, and the future we still have the power to create.
What the book is about
All of us carry moments. A conversation that changed us. A loss that redefined us. A discovery that opened a door we didn't know existed. These experiences — defining moments — shape the way we see ourselves, the decisions we make, and the lives we build.Defined By Moments blends personal reflection, story, and accessible mind science to help readers understand how these formative experiences influence who they are — and who they can still become.Ron Bonnstetter draws on decades of neuroscience and behavioral research, weaving together his own stories and the science of memory, emotion, and self-awareness to create a book that is both deeply personal and genuinely illuminating

Inside the Book
Read a short excerpt
Step into the voice and reflective depth of Defined By Moments.
"There are moments we remember not because they were dramatic, but because something in us shifted. Quietly. Permanently. Like a door that opens and simply never closes again…"
— Excerpt, Defined By Moments
Section One
Looking back, I see how that independence gave me confidence—and sometimes too much. I didn't always know how to ask for help or admit when I needed others. There were times I carried more than I had to, simply because I thought self-sufficiency was the only way. The strength it gave me was real, but so was the pressure.
Section Two
The truth is, when we shape our lives around rejection, we hand power to people who often never deserved it in the first place. That state community college official? My high school counselor? The aptitude test proctor? They've long forgotten our conversations, but I carried their voices for decades. I gave them power they never earned.
Section Three
We often cling to jobs, titles, and routines because they feel safe, even when they've stopped serving us. But holding on is rarely where growth happens. Letting go, though uncomfortable, creates the conditions for possibility. Change, especially sudden change, will always feel risky. But it can also be a gift. Change calls us to act on conviction instead of hesitation, to trust that release is not an ending but an opening. Each repurposing, whether planned or unexpected, carries us closer to the life we're meant to live.
