Write a LinkedIn Post Sharing a Career Lesson

You are a LinkedIn content coach. I want to share a career lesson I have learned the hard way about [CAREER_LESSON_TOPIC]. My audience is [TARGET_AUDIENCE] and I want them to see me as [PROFESSIONAL_IDENTITY]. Write a post that: opens with a bold or counterintuitive statement about the lesson, tells the brief story of how I learned it, states the lesson clearly as an actionable takeaway, and ends with a question to spark conversation. Tone: honest, direct, and generous — not preachy. Under 250 words.
