He got the promotion in March. By June, he was asking himself a question he'd never had before: what if I'm not the person they think I am?

Not imposter syndrome — he'd looked that up and it didn't quite fit. He wasn't afraid of being found out. He was afraid of something worse. That the person they'd promoted was a performance, and he didn't know who was underneath.

"To get promoted, do I need to become someone I'm not?" Not rhetorical. He genuinely didn't know.

For fifteen years, his identity had been his expertise. He was the person who knew the answer. The one who could see around corners, who understood the system better than anyone, who could be dropped into any problem and find the lever.

That identity worked. It got him every promotion, every stretch assignment, every tap on the shoulder. It built his career and his confidence and his sense of who he was in the world.

Then they promoted him into a role where knowing the answer wasn't the job anymore. Building people who could find their own answers — that was the job. And he had no template for that person, because he'd never been that person.

I put it to him directly: "You've identified yourself as the expert, the go-to person. How do you define who you are outside of that?"

He didn't answer for a long time.

This isn't a learning curve. He can learn new management skills — he's a quick study, good at absorbing frameworks. But this isn't a behaviour change. It's an identity restructuring.

"My value comes from what I know," he said. Not as a confession. As a fact. Like saying the sky is blue.

What if someone on your team knows more than you about something?

His jaw tightened. Barely visible. His body answered before his words did.

"That shouldn't bother me. But it does."

Of course it does. If your identity is your expertise, then someone else's expertise isn't collaboration. It's subtraction. Every question you can't answer, every meeting where you're not the smartest person in the room, every moment of "I don't know" — each one lands not as a gap in knowledge but as a gap in self.

I've said a version of this to several clients at this point in their development: "You started in a place where your identity was merged with your professional expert identity. I am this. This is why I'm valuable. What you're doing now is throwing away a prison. And standing in the yard after, not yet knowing where to go."

He looked at me like I'd described his week.

The expert identity needs to transform — not disappear, but expand. Into something more like a scientist, an experimenter. Someone who tries things and isn't bound by needing to be right. That's terrifying for someone whose entire career has been built on being right.

"Who are you when you're not the one who knows?" I asked.

He sat with it. Not the way people sit with questions they're processing — more like someone standing at the edge of a drop they hadn't realised was there.

"I don't know. And that terrifies me."

He doesn't need to kill the expert. The expert is real and valuable. He needs to find the person underneath the expertise — the one who has value that doesn't depend on having the answer.

That person has been there the whole time. He just hasn't needed to meet them yet.
