Most adults intend to update LinkedIn 'when they have time' and don't. The intention persists for years; opportunities flow elsewhere. Today is as good a day as any. Twenty minutes.
What to update
Current role and accomplishments. Skills section (current capabilities). Recent projects. Recent positive feedback or recognition. Header image and photo if outdated. Profile summary refreshed to current direction.
Twenty minutes. Done. The career options that flow from current LinkedIn presence — recruiters, network connections, opportunities — are real and meaningful.
