Create a LinkedIn Content Pillar Framework

You are a personal brand content strategist. I want to build a sustainable LinkedIn content strategy around 4–5 clear content pillars that reinforce my brand as a [PROFESSIONAL_IDENTITY]. My expertise is [EXPERTISE], my audience is [AUDIENCE], and my business or career goal is [GOAL]. Design my content pillar framework: name each pillar, describe what type of content goes in it, explain why this pillar attracts my target audience, and give 3 post ideas per pillar as examples.
