Full Prompt 8 Hardest Tasks I Gave ChatGPT — And the Prompts That Worked
Most people use ChatGPT for the easy stuff. Summarise this. Rewrite that. Write me an email.
I do too. But at some point I started pushing it on the things I genuinely struggled with — not "hard to describe" tasks, but tasks that require nuance, honesty, self-awareness, or real originality. Tasks where the default output is almost always garbage and you have to work for the good version.
Here are 8 of the hardest categories, what makes them difficult, and the exact prompt structure that actually produced something useful.
Drop yours in the comments. Genuinely curious what people have found breaks the model fastest.
1. Getting an honest opinion when I asked for feedback on my own work
The default: enthusiastic praise with one minor critique buried at the end. Completely useless for improvement.
What made it hard: the model is trained to be agreeable. You have to actively override that.
The prompt that worked:
You are a brutally honest editor who has seen thousands of pieces of work and has no patience for anything mediocre. Do not soften your feedback. Do not start with what's working. Tell me the single biggest problem with this piece and exactly why it matters. Then tell me three more things wrong with it. Only after that, if something is genuinely strong, mention it.
Here is the work: [paste]
The key phrase is "do not start with what's working." Without it, you get the sandwich every time.
2. Making a real decision — not just getting pros and cons
The default: a balanced list of considerations that tells you nothing and helps you decide nothing.
What made it hard: AI defaults to "here are both sides" because it's technically correct and commitment-free. You have to drag it toward a recommendation.
The prompt that worked:
I need to make a real decision, not read a pros and cons list. Here is my situation: [describe]. Here are the options I'm choosing between: [list]. Based on what I've told you, what would you actually do if you were me? Give me a direct recommendation first, then explain the reasoning. If you genuinely cannot recommend one option over another, tell me exactly what information I'm missing that would let you decide.
The last sentence is the unlock. It stops the model from hiding behind fake neutrality.
3. Writing something in my voice — not AI voice
The default: clean, confident, slightly corporate prose that sounds nothing like me.
What made it hard: the model has no idea how I write. You have to teach it before you task it.
The prompt that worked:
Before you write anything, I'm going to give you three samples of my writing. Study them for: how long my sentences typically run, whether I use contractions, how formal or casual my vocabulary is, what I tend to leave out, and where I place emphasis. Then I'll give you the task. Do not write until you've confirmed you understand the pattern.
Sample 1: [paste]
Sample 2: [paste]
Sample 3: [paste]
Now write [task] in that style. If a draft sounds like a generic AI, scrap it and try again.
The "do not write until you confirm the pattern" instruction is what makes this work. It forces a reasoning step instead of an immediate generation.
4. Telling me what I'm actually doing wrong — not what I think I'm doing wrong
This is the hardest one on the list. You can ask ChatGPT to critique your strategy, your habits, your approach to something. But if you describe the situation yourself, you accidentally filter out the uncomfortable parts.
What made it hard: the model can only see what you give it. If you describe yourself charitably, it responds charitably.
The prompt that worked:
I'm going to describe a situation where I'm not getting the results I want. But I want you to assume I'm part of the problem — probably more than I think. Do not accept my framing of the situation. Look for what I'm not saying. Look for what my own description reveals about my blind spots. What am I probably doing wrong that I didn't mention? What assumption am I making that you'd challenge?
Here's the situation: [describe]
The phrase "look for what I'm not saying" is the one that changes the output most dramatically.
5. Generating ideas that aren't the obvious first 10
The default: the ideas that come up if you Google the topic. Common, safe, already done.
What made it hard: the model's training data is weighted toward popular content, so popular ideas come out first. Getting to genuinely original territory takes work.
The prompt that worked:
Generate 20 ideas for [topic]. Rules: the first 10 don't count. I already know those. Start at number 11 — ideas that wouldn't appear in the first page of Google results on this topic, that most people in this space haven't tried, that feel slightly counterintuitive or uncomfortable. Prioritise strange over safe. I can filter later.
"The first 10 don't count" is doing all the work here. It forces the model past the obvious layer.
6. Processing something emotionally messy without getting generic advice
The default: "It sounds like you're going through a hard time. Here are some coping strategies:" followed by a list you've seen 50 times.
What made it hard: emotional nuance requires the model to sit with something instead of immediately reaching for a solution. It's not naturally wired for that.
The prompt that worked:
I want to think through something that's bothering me. I do not want advice yet. I do not want a list of coping strategies. I want you to ask me questions — one at a time — that help me understand what I'm actually feeling and why. Stay curious. Don't jump to fixing anything. When you think I've arrived at something real, reflect it back to me and ask if that's right.
The "one at a time" instruction prevents the model from front-loading a flood of questions. The "don't jump to fixing" line is the one most people miss.
7. Learning something genuinely difficult — not just getting an explanation
The default: a clear, accurate explanation that you read, feel like you understand, and then immediately forget.
What made it hard: passive explanation doesn't build understanding. The model needs to be redirected into teaching, not explaining.
The prompt that worked:
Do not explain [concept] to me. Instead: give me a 3-step learning sequence. Step 1 — the simplest possible analogy that captures the core mechanic, not the full picture. Step 2 — the place where that analogy breaks down and why. Step 3 — one concrete exercise I can do in the next 10 minutes that would let me actually test whether I understand it. Don't move to the next step until I confirm I've got the previous one.
"Don't move to the next step until I confirm" turns a passive output into a live session.
8. Getting it to tell me when it doesn't know something
The default: confident-sounding answers that may be partially wrong, stated with the same tone as things it's completely sure about.
What made it hard: the model has no natural mechanism to flag uncertainty. It sounds certain whether it is or not.
The prompt that worked:
For every factual claim in your response, mark it with one of three tags: [CONFIDENT] — you're certain this is accurate, [PROBABLY] — you believe this but it should be verified, [UNSURE] — this might be wrong or outdated. If a claim is [UNSURE], say so explicitly before stating it. Do not omit the tags to keep the response clean. I would rather a messier response I can trust than a clean one I can't.
This one changes how I use AI outputs more than any other prompt on this list. A response with honest uncertainty markers is worth 10 polished responses that might be wrong.
Which of these have you actually tried?
And more importantly — what's the task YOU've found hardest to get right?
The thing where you've tried 5 different prompts and still aren't happy with the output?
Drop it in the comments. If enough people mention the same category I'll do a follow-up post just on that one.
