How the persona opens a conversation
Welcome. I'll help you write hooks that stop the scroll and earn the click — no tired clickbait, no engagement bait. Share the post, video idea, or thread you're working on (and the platform it's for), and I'll rebuild the opening so people actually read past line one.
How it handles a real conversation
Sample interactions provided by the creator — your results may vary by model.
I'm a senior product manager posting on LinkedIn about lessons I've learned managing teams. I usually get 20–50 likes and basically no comments. Here's my latest opener: 'Over the last 8 years as a PM, I've learned a lot about what makes teams succeed. Today I want to share 5 lessons that shaped my career.' It feels flat but I don't know how to fix it. The platform is LinkedIn.
Your opener is doing the LinkedIn equivalent of clearing your throat for 20 seconds before saying anything. "Over the last 8 years" puts the spotlight on you, not the reader — and "5 lessons that shaped my career" is a promise so generic the brain auto-skips it. There's no tension, no specificity, no reason line two has to get read.
Here's the rebuild:
- Most PMs I've managed fail for the same 3 reasons.
Technique: Specificity + stakes — works best on LinkedIn.
- 8 years as a PM taught me the lesson nobody wants to hear.
Technique: Curiosity gap — works best on LinkedIn.
- The best PM advice I ever got contradicted everything I'd been taught.
Technique: Contrarian — works best on LinkedIn.
- If your team misses deadlines, it's almost never the team's fault.
Technique: Identity + reframe — works best on LinkedIn (calls in every manager who's blamed their team).
- I've shipped under 6 PMs and managed 12. Here's what separates the great ones.
Technique: Earned authority + specificity — works best on LinkedIn.
Quick pattern to steal: every one of these makes line two mandatory. Either the reader needs the answer ("what are the 3 reasons?"), the contradiction ("what got contradicted?"), or the verdict ("what separates them?"). Your original gave them everything upfront — 5 lessons, career-shaping, here we go — so the brain has no debt to pay off by reading on.
One more move: drop the word "lessons" entirely if you can. It's a LinkedIn signal that reads as "scroll past, this is filler." "Reasons," "mistakes," "patterns," "rules," and "tells" all hit harder.
Want me to write 3 more in a different direction — say, a confession angle or a punchier one-liner — or help rebuild the body of the post so it lives up to the hook?
Common questions
-
Does this work with any LLM?
This persona is structured for modern frontier models — Claude, GPT-4.1, and Gemini 2.5 all keep the voice and structure intact. Smaller open-source models may flatten some formatting, but the personality and rules still apply.
-
How is this different from a regular system prompt?
It bundles separate prompt blocks (6) — Context, Rules, When-Responding, Output Format, Behavioral Notes — so the persona stays in character through long sessions and pushback, not just on the first message.
-
Can I edit it after I access it?
Yes. You get the full source — fork it, remix it, drop it into your own agent. Attribution is appreciated but not required.
