There is a specific discomfort that arrives early in a career transition that nobody warns you about. It isn't financial anxiety, though that's real enough. It isn't the practical uncertainty of learning new skills or navigating an unfamiliar industry. It's something quieter and more unsettling than either of those things.
It's the feeling of no longer knowing who you are at work.
For years — maybe a decade or more — you've had a version of yourself that functioned smoothly in a professional context. You knew the landscape. You knew how to read a room, how to handle the difficult conversations, how to do the thing well enough that you didn't have to think about doing it. That competence became part of your identity in a way that's easy to underestimate until it's no longer there.
And then you step into something new, and suddenly you're a beginner again. Not in skills only — in self. The confident professional you'd quietly become has no purchase here yet. You're back to watching how other people do things, unsure whether you're reading situations correctly, uncertain whether your instincts apply. It's not failure. It's just unfamiliar. But it can feel remarkably like failure, and that's worth understanding.
What the research says about this particular discomfort
Herminia Ibarra, a professor of organisational behaviour at London Business School, has spent years studying how people navigate professional identity during career transitions. In a 1999 paper published in Administrative Science Quarterly, she described how people adapt to new professional roles by experimenting with what she called provisional selves — tentative, trial versions of a professional identity that haven't yet solidified into something stable.
Her research found that this experimentation is not a sign that something has gone wrong. It is the mechanism by which a new professional identity forms. People in transition observe others who seem to embody aspects of the role they're moving toward, try on elements of those identities, and then evaluate those attempts against both their own internal sense of self and the feedback they receive from their new environment. The process is iterative and often uncomfortable — and it is, she argued, how adaptation actually works.
What Ibarra's framework makes clear is that the discomfort of early career transition is not evidence of a mistake. It is evidence that the process is working as it should. The instability isn't a problem to be solved. It's a phase to be moved through.
The competence you're mourning
This is the author's own observation rather than a research finding, but it's one worth naming: part of what makes a career transition genuinely hard is that it involves a kind of grief that is difficult to articulate.
You are not only leaving a job. You are leaving behind a version of yourself that was good at something. The fluency you'd built — the way difficult problems felt manageable, the way you could navigate your field without conscious effort — that doesn't transfer automatically. In the new context, you lose access to it temporarily. And because professional competence had become quietly woven into your sense of self-worth, losing access to it feels more personal than it should.
This isn't weakness. It's a predictable feature of how professional identity works. The more deeply you'd invested in a particular role or field, the more disorienting it will feel to step outside it. That's not a reason to stay. But it is a reason to be patient with yourself during the period when you don't yet feel like yourself in the new context.
The trap of performing your old self
One response to this discomfort — and a common one — is to try to import the old professional identity wholesale into the new context. To lead with the expertise from your previous field even when it doesn't quite apply. To reassert the confident, competent version of yourself before you've actually built the foundations for that confidence in the new environment.
Ibarra's research on provisional selves suggests why this tends not to work well. Adaptation in a new professional context requires a degree of openness to genuinely not knowing yet — to observing, experimenting, and letting feedback shape you. Arriving with a fully formed identity that you're not willing to revise closes off the very process through which a new professional self gets built.
The more useful approach, her research suggests, is to hold the old competence and identity lightly — as context you're bringing with you, rather than armour you're defending. The skills and judgment you've built are real and they matter. But they need time to find their application in the new setting, and that takes longer than most people expect or allow themselves.
What actually helps in the in-between
The period between leaving one professional identity and arriving at the next is genuinely uncomfortable, and there isn't a way to skip it. But there are ways to move through it with more steadiness.
One is simply naming it accurately. The discomfort of a career transition is not the same as the discomfort of being in the wrong place. It is the discomfort of being in the right place at an early stage. Recognising the difference doesn't make the feeling go away, but it changes what the feeling means — which changes how much weight you give it.
Another is finding small, concrete evidence of progress rather than measuring yourself against the fully formed professional you'll eventually become. Ibarra's framework implies this: the provisional self is evaluated incrementally, through small experiments and their outcomes, not through a single definitive assessment. Each conversation that goes well, each problem that yields to your approach, each moment of genuine competence in the new context — these accumulate into a new professional identity more reliably than any amount of self-persuasion.
The last is one that applies to every transition but especially to career change: the person you were at the end of your previous career — competent, fluent, sure-footed — took years to build. The person you'll become in the new one will too. That isn't pessimism. It's just an honest account of how professional identity forms, and a reminder that the discomfort of not being there yet is not the same as evidence that you won't get there.
