Most women under-promote their work. The cultural messaging against 'bragging' contributes; cumulative effect over a career is significant. Comfortable, professional self-promotion is a learnable skill — and one that materially affects compensation, opportunities, and advancement.
What good self-promotion looks like
Sharing project completion with managers and stakeholders ('we delivered X, here's the outcome'). Naming your contribution explicitly in team updates. Volunteering to present your team's work to leadership. Writing about your professional area publicly. None of this is bragging — it's information sharing.
What undercuts (often unconsciously)
Using 'we' when you mean 'I'. Adding caveats ('it wasn't much really'). Crediting team for your individual contribution. Skipping presentation opportunities because you don't want attention.
Notice over the next month: how often do you accurately attribute work to yourself in professional contexts? Most women undershoot by significant margins. Calibrate upward; observe what changes.
