Why it worked

Leads with a specific number, which is concrete enough to be worth a second of attention.
Uses concrete numbers instead of vague claims, which makes it credible and quotable.
Follows a clear Hook → Context → Context → Landing shape, so the reader always knows where they are.
Ends on a short line that is easy to quote and repeat.
The opening line stands alone, so it reads completely before the post is expanded.
Written from experience rather than as advice, which is harder to argue with.

The mechanics

Hook: Leads with a number
Structure: Hook → Context → Context → Landing
Style: Conversational paragraphs at a steady pace.
