You’ve met them. The person who, when they start talking about their thing, transforms.
Maybe it was a tour guide. A train enthusiast on a platform. A colleague who lights up when the conversation finally turns to the topic they actually care about. Two minutes ago the exchange was polite and a bit flat. Now they’re glowing, and you find yourself glued, learning things you didn’t know you wanted to know.
Someone described one to me recently that’s stuck with me ever since.
The cathedral guide
On a trip, they were shown around a cathedral by a guide whose entire world, as far as they could tell, was a single tomb. And not just the stone of it, though he could talk about the carving for an hour: the choices, the craft, the history packed into the material itself. It was the whole story. The figure buried there, someone of real historical importance, the dramatic life that landed them in that spot, and the place they still hold in the history books. The stonework and the person and the centuries, all at once.
What struck them wasn’t just the knowledge. It was the attunement. He’d step forward into his subject, fully alight, and then, sensing the group, step back to read the room. If the interest was there, he’d step back in and go deeper. If it wasn’t, he’d ease off. He was lit up and present at the same time, and the combination was magnetic. It was, they said, one of the most memorable moments of the whole trip.
They came away having learned more about that cathedral in five minutes than any guidebook could teach. Not because the guide had more facts. A book has more facts. Because the facts arrived on fire.
Joy is the most infectious teacher
There’s something about watching a person fully absorbed in what they love. It’s not just informative. It’s contagious. Their state transmits. You leave a little more alive than you arrived.
Steve Jobs understood this. The “one more thing” at the end of his keynotes worked not because of the product spec, but because the man on stage was genuinely, visibly thrilled about it. We weren’t buying features. We were catching his joy.
We tend to treat this as a nice bonus, a bit of personality on top of the real content. I’d argue it is the content. The passion isn’t decoration around the knowledge; it’s the delivery mechanism that makes the knowledge land and stick.
Autistic joy, and the cost of dimming it
Among the neurodivergent people I work with, there’s a particular flavour of this I’ve come to treasure. Sometimes it’s called autistic joy: the deep, total, luminous absorption in a special interest. The capacity to care about something with an intensity that most people reserve for very little.
It’s a real and underappreciated variety of joy, and I want to name it specifically, even though some argue the label is too narrow, that joy is joy, and we shouldn’t fence it off. There’s truth in that. But there’s also something worth honouring in the particular, often-misunderstood version that gets a person obsessing happily over cathedral stonework, or train timetables, or a corner of their work that nobody else has the patience to love.
Because here’s what so often happens to it: it gets dimmed. Somewhere along the way, the lit-up child is told they’re “too much.” Tone it down. Read the room. Be more measured, more professional. And they learn to put the fire away, to mask the very thing that made them most alive and most able to teach.
What a loss. Not just for them, but for everyone who would have caught it.
The leadership lesson
If you lead people, there are two invitations here.
The first is about you. Where’s your version of the cathedral guide’s tomb, the part of the work you could talk about for an hour without noticing the time? Most leaders have been trained to flatten that into neutral competence. But your team doesn’t catch fire from your competence. They catch it from your aliveness. Leading from the thing you genuinely love is not unprofessional. It’s the most persuasive thing you can do.
The second is about them. Every person you lead has a tomb of their own: a place where their attention goes willingly and their best work lives. Your job isn’t to flatten everyone to the same measured register. It’s to notice where each person lights up, and to build the role around that as much as you can. Not “be more like everyone else,” but “where does your particular fire belong?”
The cathedral guide knew when to step forward and when to step back. That’s the whole art: letting the joy lead, while staying attuned to the room.
Try this
This week, when you catch someone lighting up about their thing, really catch it. Don’t politely wait for them to finish. Lean in. Ask the next question. Let yourself be taught by their joy.
And notice your own. The thing you’d happily bore a stranger about? Stop apologising for it. That fire is not a flaw to manage. It might be the best thing you bring.
