Generate opening-line variants for social posts

Write opening-line variants for this post.

Produce eight, each a different angle:
1. A specific number or fact
2. A common belief you are about to contradict
3. A mistake you made
4. A question the reader has already asked themselves
5. A scene, mid-action
6. A direct address to a narrow group
7. The conclusion, stated flatly up front
8. A comparison that reframes the topic

For each: the line, who stops for it, and what the post must then deliver.

Rules:
- *Banned*: "Most people don't know", "Here's the thing", "Let me tell you", numbered-list teasers, and anything that promises more than the content delivers.
- The hook must be honest about what follows. A hook that over-promises costs more in trust than it gains in views.
- Use only my material. Do not invent a statistic or an anecdote for the sake of a stronger hook.
- Mark any variant that would work on one platform but not the stated one.
