Common Prompt Mistakes (And How to Fix Them)
Even experienced AI users make these errors. Learn to spot and fix them.
Mistake 1: Being Too Vague
Bad: "Help me with sales"
Fix: "Create a cold outreach email template for selling our B2B accounting software to CFOs at mid-size companies (100-500 employees)"
Mistake 2: Asking Multiple Unrelated Things
Bad: "Write me a blog post about AI, also fix this Python code, and what's the weather?"
Fix: One prompt per task. Or explicitly separate them: "I have 3 unrelated requests. Please address each separately."
Mistake 3: Not Specifying Format
Bad: "Give me marketing ideas"
Fix: "Give me 10 marketing ideas for a local bakery, formatted as a numbered list with a one-sentence explanation for each"
Mistake 4: Forgetting the Audience
Bad: "Explain machine learning"
Fix: "Explain machine learning to a small business owner who has no technical background, using everyday analogies"
Mistake 5: Not Iterating
Many people take the first output and give up if it's not perfect. AI conversations are iterative.
First prompt: [Get initial output]
Follow-up: "Good start, but make it more concise and add specific dollar amounts"
Follow-up: "Perfect. Now adapt this for an email format instead of a report"
Mistake 6: Overloading Context
Don't paste 50 pages and say "summarize this." Instead:
- •Break large documents into sections
- •Tell the AI what to focus on
- •Ask specific questions rather than open-ended ones
Mistake 7: Anthropomorphizing
Bad: "I hope you're having a good day! I was wondering if maybe you could possibly help me..."
Fix: Just state what you need. The AI doesn't have feelings and politeness tokens cost money (though being respectful is fine).
Mistake 8: Not Verifying
Taking AI output at face value without checking facts, calculations, or code. Always verify anything you'll act on.
Exercises
0/3What is wrong with the prompt: "Help me with sales, fix my code, and plan my vacation"?
Find an AI conversation you've had before (or create one with a vague prompt). Identify which mistakes from this lesson were present, and rewrite the prompt to fix them. Test both versions.
Hint: Look for: vague language, missing format specs, no audience, no iteration.
Why is not iterating considered a mistake?
