When you are embedded in an organisation, your professional identity is partly assumed. The brand does some of the work, as does your title. The organisational context explains what you do, so you rarely have to.
When the context changes, suddenly you are expected to articulate, from scratch, the thing that was always there, but never needed saying. Your editorial through line. The unique value you offer.
The hardest part isn't confidence. It's that the thing you most need to see clearly about yourself is the thing you are least able to see. That's what a genuine conversation surfaces — and what you cannot do alone.
