The Two Sides of How a Leader Leads
Lead with Light™ lives at the intersection of logic and light, competence and character, systems and soul. I call it rigor and radiance
Rigor and Radiance
Most leadership development obsesses over rigor because rigor is measurable. You can certify it. Test it. Put it on a résumé. Radiance gets dismissed as soft, unteachable, or worse. Nice to have when business is good, and the first thing cut when pressure rises.
That dismissal is hogwash.
The leaders who shape people and outcomes carry both. Without rigor, radiance is charm without substance. Without radiance, rigor is cold competence. Neither is enough on its own. The HOW of leadership has two dimensions, and most leaders are predominantly operating from only one of them.
Last year, I discovered Vanessa Van Edwards. She’s done brilliant work on the behavioral science of human connection.
In her book Cues: Master the Secret Language of Charismatic Communication, she explores what she calls competence and warmth. The observation stuck with me. Most people, she argues, project one of those qualities strongly and the other weakly. The rare few project both and are perceived as having charisma.
I sat with that idea for a long time before it found its way into Lead with Light™. Competence and warmth gave me the foundation. Rigor and radiance is what grew out of that foundation when I started asking what the words look like inside a leader’s actual practice. They’re the behavioral expression of a larger system, a way of leading anchored in purpose and virtue.
Rigor is the substantive HOW.
Education, knowledge, experience, hard skills, sound judgment, the discipline to do the work properly. It shows up in how a leader thinks, analyzes, decides, and acts, especially when the pressure is on and the stakes are high.
Radiance is the relational HOW.
Warmth, presence, approachability, and the behavioral expression of virtue in action. It shows up in how people feel when this leader walks into the room and lingers long after they’ve left.
Both are qualities of the HOW.
Neither is a quality of the WHAT. The WHAT is the result. The HOW is the way the leader gets there, and the way the people around them experience the journey.
Radiance isn’t Charisma
This is the trap I want to call out early.
Charisma and radiance look alike from a distance. Up close, they behave very differently. Charisma can be performative. It can hide a personal agenda. It can draw people in for reasons that have nothing to do with serving them.
While charisma is often ego-driven and self-serving, radiance is virtue-driven action in the service of others.
I’ve worked with leaders who had enormous executive presence and big personalities. People were drawn to them in droves. Watch them long enough, though, and you saw what they were really doing. The warmth was a tactic. The smile served a purpose, and the purpose was usually revolved around themselves.
That’s not radiance. That’s stagecraft.
Real radiance is authentic and generous.
You feel it because the leader truly cares about you and what you think. Their confidence is mixed with humility, and you can tell the difference within minutes of being in the room with them.
Radiance, in the way I mean it, isn’t a leadership technique. It’s not a life hack designed to win others over or gain influence. It’s the visible expression of who a leader is becoming.
Radiance radiates from a burning desire to serve others.
The leader genuinely cares about people and about making the world a better place. They carry a purpose that sparks energy and excitement, and the excitement is contagious.
They’re comfortable in their own skin, and they don’t feel the need to perform. Nothing magical happens when they scan their security badge at the door. They show up, and they’re the same in public as they are in private.
That last part is the test many leaders fail. Radiance is what lingers when the audience is gone.
What Radiance Looks Like
Think about the people you’ve watched do this well.
Whatever you think of his politics, Barack Obama caused a shift in the room that almost everyone recognized when he walked in. Oprah Winfrey has built a career on making whoever she’s speaking with feel like the most important person in the world. Tom Hanks has decades of stories from crew members and strangers about the way he treats people who can do nothing for him.
The behaviors aren’t complicated. A smile. A wave. Eye contact that lingers a beat longer than necessary. Hand gestures that gather a room in rather than push it back. Questions that signal genuine curiosity instead of polite ritual.
What’s difficult isn’t the behavior. What’s hard is the orientation underneath. These people walk into a room thinking about the people they’re about to meet. The behaviors flow from the orientation, not the other way around.
I saw the same quality up close in Peter Lilly, a senior executive I worked with at Cox Communications, now retired.
Peter is the real deal, an extremely competent leader. At the same time, he’d walk into a room and within seconds the temperature would change for the better. Not because he was loud or theatrical, but because he genuinely cared and wanted to be there with the people in front of him.
Peter possesses a strong executive presence because his confidence and humility work together. You feel seen by him, and you feel that whatever he’s about to say is meant to serve you and the team, not him.
That’s radiance. And it’s a characteristic you can develop if you’re willing to do the inner work first.
How You Actually Develop Radiance
So how do you develop or strengthen it?
Start with Vanessa Van Edwards. Her YouTube content is a brilliant on-ramp. She teaches the behavioral science of cues, signals, and warmth in ways that translate directly to how you carry yourself in a room. Consume it, study it, practice it. That’s the foundation.
A word of caution. When you’re learning, it’s normal for it to feel a little uncomfortable. Start small. One behavior at a time. And understand that if you stop at simply learning and executing the techniques, then you’re bordering on performative. The cues become a costume. Radiance grows from genuinely thinking about and caring for others. If it doesn’t, the room will sense the gap right away.
Here’s where the inner work lives.
Know what you stand for.
Radiance emanates from leaders who are comfortable in their own skin. That comfort comes from clarity about your values, your purpose, and the way you want to show up in the world. Vague leaders can’t radiate. Leaders anchored in principle can’t help it. Radiance grows from virtue. From integrity. From genuine care for others. From standing on principle.
Slow down.
Most rigor-first leaders move too fast through rooms. They’re thinking three steps ahead, easily distracted by their phone, and eager for what’s next. Radiance asks for the half-second of pause. The eye contact held a beat longer. The question asked instead of the statement made.
Be curious, not impressive.
Walk into rooms with curiosity and questions, not answers. Be observant. When you’re focused on what you’re about to learn from the people in front of you, the orientation does most of the work.
Practice in low-stakes moments.
You don’t develop radiance on the big stage. You develop it in the elevator, the hallway, the coffee line. The big stage is where the practice shows.
Ask for the feedback you’d rather not get.
Find the people who’ll tell you the truth and ask them what you’re like to be around. Most leaders never ask. The leaders who do, grow.
The Rigor Side
I want to spend a moment defending rigor, because the radiance crowd sometimes undervalues it the way the rigor crowd dismisses radiance.
Warmth without competence is a problem.
We’ve all worked for the lovely person who couldn’t decide, didn’t know the business, missed or didn’t understand the technical details that mattered, and left their team to clean up the resulting mess. That leader is approachable, likeable, maybe even kind, and the team still suffers.
Rigor is the discipline that earns you the right to lead.
It’s the hours spent learning the discipline or craft. The willingness to be precise when precision matters. The judgment that comes from having done the work, made the mistakes, and built pattern recognition over years.
A leader who carries rigor without radiance can still produce results. A leader who carries radiance without rigor can still inspire people, briefly. The leader you’re inspired to follow, and the leader you want to become, carries both.
Rigor is what you know. Radiance is what they feel.
My Own Honest Read
Here’s where I feel compelled to be transparent.
I’ve done the integration work. Rigor came more naturally to me. Radiance, I had to learn, and over the years I’ve gotten comfortable carrying both. In coaching, in small groups, in one-on-one conversations, I’m at home. People who’ve worked with me and know me well will tell you they feel both the substance and the warmth. It wasn’t always that way.
What I’ve never been fully comfortable with is the big stage.
For most of my career, I was the person behind the camera. I coached the executive who was about to go on stage. I prepped the leader who was about to face the cameras. I built the message, shaped the delivery, sat in the back of the room, and watched it land. I was good at it. I loved it. I never wanted the spotlight on me, mainly because it was outside my comfort zone. That’s been changing. What’s making it easier is a shift in orientation. It’s not about me. It’s about the message: whisper yearning to be a roar.
The work I’m doing now with Lead with Light™ is asking me to step in front of the camera, not remain behind it. To get on bigger stages. To carry the message myself instead of preparing someone else to carry it. The old discomfort is still there. I’m an ambivert most at home in deep conversation, and the bigger the room, the more energy it takes to stay in the radiance lane.
There are leaders out there who already sense that HOW they lead matters as much as WHAT they achieve. They feel the gap. What they may not see yet is that the HOW has two dimensions, and both are worth the work. That’s the message I’m learning to carry. When I remember the message is the point, the stage feels smaller, and the room feels warmer.
Here’s the lesson I would’ve loved to learn at twenty-something.
Carrying rigor and radiance well in the rooms where you’re comfortable is the first half of the work. Projecting both when the room is bigger than your comfort zone, that’s the second half.
Most leaders never get to the second half because they assume the discomfort means the qualities aren’t real. They’re real. They just need a bigger container.
When you project your light, the spotlight isn’t on you. Your light brightens and warms the room for others. Holding back isn’t humility. Holding back is hoarding a gift that isn’t yours to keep.
Why This Matters for How You Lead
Rigor and radiance both demand attention and development. Neither is a given. Both ask you to do uncomfortable work over a long arc.
Questions Rigor and Radiance Ask
Rigor asks you to learn, to practice, to take feedback, to keep building competence long after the credential is on the wall. Radiance asks you to know what you stand for, to be comfortable in your own skin, and to stop performing long enough to see and listen to the people in front of you.
Leaders comfortable in both dimensions produce something rare: confidence rooted in identity. They know what they’re capable of and they know what they value. They handle hard situations because they’ve prepared for the substance, and they’ve practiced the presence. Their teams feel it. Their results show it.
And for leaders who already carry both well in close quarters, the work is to keep growing the container. Bigger rooms. Bigger stages. Bigger reach. The qualities don’t change. The projection does.
You never quite finish this work.
You tend it, like a flame you keep coming back to, brighter each time. Monthly check-ins with people you trust. Quarterly reflection on what’s growing and what’s gone quiet. Consistency beats intensity, and it compounds.
How we do what we do — how we lead — is just as important as what we achieve. Rigor and radiance is the working language for what that HOW looks like in practice.
Parting Thoughts
Here’s something to do this week.
Before your next meeting, pause for five seconds at the door. Ask yourself one question: Am I about to walk into this room thinking about myself, or about the people in it? If the answer is yourself, take another breath and shift. The five seconds will change what happens in the next thirty or sixty minutes.
That’s the work. Small, repeatable, unglamorous. Rigor and radiance get built in hallways, not on retreats.
If you read this and recognized yourself as a rigor-first leader, you’re in good company. The work for us, and I’m including the version of myself still learning to project at scale, is to stop dimming. To let what’s already inside us reach the people around us. To trust that our light isn’t a distraction from the work. It’s part of how the work is received.
If you read this and recognized yourself as a radiance-first leader, the work is to keep building substance. Make sure the warmth is anchored to real competence, analytical thinking, and sound judgment. People will follow you for a while on charm. They’ll stay because of what you truly know and how soundly you decide and execute.
Either way, the framework holds. Both qualities. Both dimensions. Both are worth the work.
Where do you sit on the spectrum? Which side has the most growth ahead of it for you?
