Stop Building on Bad Assumptions 🛑

April 13, 2025

Happy Sunday!

Ever pour weeks into a plan—only to realize it was built on the wrong assumptions?

No one challenged your thinking.
No one spotted the flaw.
And now you're down time, money, and momentum.

That’s what today’s newsletter fixes.

We’re dropping Part Two of the Prompt Productivity Series—built to save you from blind spots, guesswork, and “I should’ve seen that coming.”

🔁 Quick Recap:

Last week, we turned LLMs into your 24/7 tutor.
No more waiting, no more endless tutorials. Just answers—tailored to you.

This week? We’re getting surgical.

🚨 The Real Problem: Building in a Vacuum

If you’re a builder or creator, you’ve felt it:

You get excited.
You make the plan.
You start executing...

But no one challenges the logic.
So you launch—and realize:

  • You solved the wrong problem

  • You targeted the wrong audience

  • Or worse, no one wanted what you made

The real culprit? Uncertainty.

You think the idea is solid, but:

  • What if there’s a flaw you missed?

  • What if the market doesn’t care?

  • What if your logic is built on inaccurate assumptions?

🥋 The Fix: A Strategic Sparring Partner (That’s Always There)

Imagine someone on your team whose only job is to poke holes, challenge your thinking, and sharpen your ideas—before they cost you.

That’s what this week’s prompt turns your LLM into.

It asks:

  • Are you solving a real problem?

  • Have you tested your riskiest assumption?

  • Where’s the weak link?

This isn’t friction that slows you down—
It’s the kind that saves you from wasting your shot.

⚙️ This Week’s Tool: The Idea Stress Test

Most ideas die when they hit the real world.

This prompt acts as your pre-launch gut check, surfacing:

  • Blind spots

  • Hidden assumptions

  • Missed risks

  • Simplification opportunities

How to use it:
Copy the prompt → Paste your idea → Brain dump everything.

The LLM will break it down and show you exactly what needs work.

Because the smartest move isn’t doing more—
It’s thinking better.

📌 The Prompt:

[You are a world-class business strategist trained to spot blind spots, flawed assumptions, and untested risks in early-stage plans.
You specialize in helping founders, operators, and creators stress-test their strategies before they waste time or money.
I will paste a business plan, idea, or system below.
Your job is to:

Ask 5–7 sharp, clarifying questions that expose what’s missing or unclear

List 3–5 potential risks, blind spots, or edge cases the creator might not have considered

Point out any hidden assumptions or logic jumps in the plan

Suggest 1–2 ways to strengthen or simplify the plan if possible

Be direct but constructive — I’m not looking for flattery. I want strategic clarity.

Output your response in a structured format with clear headers like:

Questions

Risks & Edge Cases

Assumptions

Suggestions

🧠 Real-World Example:

Let’s say you’re launching a side hustle:

“I want to open an Etsy store selling funny custom mugs. I’ll design them with Canva, use Printify for fulfillment, and post on Instagram to drive traffic.”

Drop it into the prompt above, and the LLM might return:

Questions

  • Who’s your exact target beyond “people who love coffee and sarcasm”?

  • What’s your strategy to drive consistent traffic beyond Instagram?

  • What makes your designs stand out in a crowded market?

  • Have you tested if people will actually pay for your humor?

  • What’s your plan for customer service and returns?

Risks & Edge Cases

  • Low visibility on Etsy without early traction

  • Copyright issues from trending meme use

  • Printify delays hurting customer satisfaction

  • Low margins eating into profit

Assumptions

  • Instagram followers = buyers

  • Everyone loves sarcasm

  • Canva designs can compete on Etsy

Suggestions

  • Start with fewer designs and test with a niche audience

  • Layer in a storytelling strategy via TikTok or email

  • Consider bundles or seasonal launches for repeat buyers

✅ What This Unlocks:

  • Shows you what you couldn’t see before

  • Stops costly mistakes early

  • Sharpens ideas before launch

  • Feels like a $500/hour strategist is reviewing your plan

That’s Part Two of the Productivity Series.

So—what’s your next move?

You’ve now got a personal sparring partner that cuts through fluff, exposes flaws, and makes your ideas real-world ready—before the world ever sees them.

Use it. Let it sharpen your strategy.
Then launch with eyes wide open.
