In our training sessions at Braintrust, we often show a picture of a caterpillar going through the transformation to a butterfly. When we ask participants what they see, the answers move through a predictable progression: "a caterpillar," then "a butterfly," then "a caterpillar changing into a butterfly," and finally the word that changes everything — metamorphosis. Then comes the real insight: once the butterfly has emerged, it cannot go back.
That image is not just a metaphor. It is a model for what happens when a human being connects deeply with their why. When someone truly understands the reason behind what they do, they undergo a kind of metamorphosis. And like the butterfly, they do not go back.
The Moment That Changes Direction
Have you ever had a moment — one you can look back on and recognize as a genuine turning point? Not a decision you made with full clarity, but a pull you felt that you couldn't quite explain at the time?
In 2015, after 25 years in the pharmaceutical industry, I had that moment. I made the unusual decision to apply for a position in the management Ph.D. program at Case Western Reserve University. If you're wondering who begins a doctoral program 25 years into a career, I understand the skepticism. I couldn't explain it to my wife. I couldn't explain it to myself. All I knew was what I was about to do. The why was still somewhere ahead of me.
That usually doesn't last long. What without why is not sustainable. Purpose is the engine beneath behavior, and without it, even the most ambitious actions run out of fuel.
The Phone Call That Named It
On August 24th, 2015, I was driving from Cincinnati to Cleveland to begin the program. My brother called. He asked a simple question: "Why are you starting this journey?"
After a brief conversation, I said a word I hadn't planned to say: transformation. Not incremental change, not a credential, not a career move. Transformation. The kind where you don't go back.
At 6:00 AM the next morning, I wrote a note to myself: "Transformation — let the journey begin." I still carry that note. The destination wasn't clear then, and in some ways it never fully is. But the direction was. I wanted to do something that would have a lasting impact on others. Something that would make a difference.
What Without Why Is Unsustainable
There is a reason why clarity of purpose precedes sustained action. Neuroscience bears this out: when behavior is not grounded in an emotional and values-based foundation, the prefrontal cortex works harder to maintain it. Decisions made purely from logic, obligation, or external pressure require far more cognitive energy to sustain than those rooted in genuine purpose.
In other words, knowing what you want to do without knowing why you want to do it is like trying to navigate without a destination. You might move, but you won't know when you've arrived — or why you're still going.
Purpose is not a luxury for philosophers. It is a practical operating condition for anyone who wants to lead, coach, or develop others over time. The leaders and coaches who sustain their commitment through difficulty are almost always the ones who can articulate a clear why, not just a clear what.
Your Why Connects You to Your Sages
As a coach and professor, I have spent hundreds of hours coaching individuals and reading their why stories. What strikes me every time is how those stories connect to Sages — the people in our lives who have shaped what we believe, how we see the world, and what we value most.
A Sage might be a parent, a coach, a teacher, a mentor, or someone you barely knew who said something that rewired how you understood yourself. When you trace your why back far enough, you almost always find a Sage. And when you understand that connection, something shifts. You stop treating your motivation as a personal quirk and start recognizing it as something with roots, with history, with meaning.
That recognition changes how you lead. It changes how you coach. And it changes how you connect with the people around you.
Why We Ask "What" Instead of "Why"
Here is the question I keep returning to: if understanding someone's why is so powerful, why is our default instinct to ask people what they do rather than why they do it?
Part of the answer is habit. Most professional contexts train us to lead with credentials, roles, and responsibilities. "What do you do?" is the opening move at almost every professional introduction, every dinner party, every networking conversation. It is efficient. It sorts people quickly. But it misses almost everything that matters.
When you ask someone what they do, you learn their job. When you ask them why they do it, you learn who they are. And who they are is where real connection — and real coaching — begins.
Asking "Why" in Real Conversations
The next time you sit down with someone — whether it's a 1:1 with a team member, a conversation over coffee, a call with a family member, or a dinner with someone new — try starting with this question: "Why do you do what you do?"
Then be quiet. Listen without an agenda. You will hear stories you did not expect. You will learn things about that person that their job title would never have revealed. And in many cases, you will watch someone visibly shift — because being asked why is an unusual and meaningful experience. Most people are never asked.
What you're creating in that moment is not just a better conversation. You're creating the conditions for genuine trust. And trust, as we know from the neuroscience, is the prerequisite for everything else: real feedback, real growth, real collaboration.
The Science of Helping People Change
During my Ph.D. program, I had the privilege of being mentored by Richard Boyatzis, Ph.D., one of the foremost researchers in intentional change theory and coaching science. In his book Helping People Change (co-authored with Melvin Smith and Ellen Van Oosten, published by Harvard Business Review Press), he offers a definition of a coach that I return to often:
"Facilitative or helping relationships with the purpose of achieving some type of change, learning, or new level of individual or organizational performance."
What strikes me about this definition is how much weight it places on the relationship itself. Not the technique. Not the framework. The relationship. And relationships are built, at their core, on understanding. Understanding what someone values, what they fear, what drives them — and yes, why they do what they do.
The most effective coaches are not the ones with the best playbook. They are the ones who understand the person in front of them deeply enough to meet them where they are and help them move toward where they want to go.
Transformation That Doesn't Go Back
The butterfly cannot return to the cocoon. That is not a limitation — it is the point. Metamorphic change, by definition, is irreversible. When you truly understand your why, and when you help the people around you understand theirs, you are not making incremental improvements to their performance. You are initiating a shift in how they see themselves and how they operate in the world.
That kind of transformation is what the best leaders and coaches are actually after. Not a better quarter. Not a cleaned-up 360. Something more lasting: a person who leads differently because they understand themselves differently.
That journey begins with a single question. And it begins with the courage to ask it — of yourself, and of the people you are trying to develop.
If you want to build strong relationships in business and in life, take the time to understand the why of the people around you. It will begin a journey of transformation that neither of you will want to reverse.
At Braintrust, the work of NeuroCoaching is built on exactly this foundation. If you're thinking about what it looks like to bring that practice into your leadership team or your organization, let's start a conversation.
