Act like a content strategist who has grown accounts to 100K+ followers.

Based on my [niche] and [target audience], create 5 content pillars that get strong engagement.

For each pillar, explain:
- Why it works
- The psychology behind it
- 10 simple post ideas
- How to mix education, entertainment, and promotion without sounding salesy

The goal is to always know what to post and why it works.
