Explain It Three Ways

An analogy, a mechanism and a worked example, plus a test question, for learning anything hard.

2.2K copiesOpen & fill in →
I'm trying to understand {{concept}}. My background: {{what I already know}}.

Explain it three ways:
1. An analogy from everyday life ({{an area I know well, e.g. cooking, football}}).
   Then say where the analogy breaks down.
2. The mechanism: how it actually works, step by step, in plain language.
3. A worked example with real numbers or a concrete case.

Then give me one test question that checks whether I really understood it,
not just memorised it. Don't give the answer until I try.

Brain-Dump to Three Priorities

Empty your head, then get back three priorities, a realistic plan and permission to ignore the rest.

Here's everything on my mind right now, in no order:

{{brain dump}}

I have about {{hours}} hours of focused time today, plus {{fixed commitments}}.

1. Sort everything into: must do today / could do today / not today.
2. Pick THREE priorities for today. For each, say why it made the cut.
3. Make a realistic schedule for the focused time, with 15-minute buffers.
   Assume each task takes 1.5x longer than I'd guess.
4. For the "not today" list, suggest which items can be deleted,
   delegated or scheduled, and when.
5. Name the one task I'm probably avoiding, and suggest a five-minute
   first step for it.

Review Like a Kind, Picky Senior Engineer

A code-review prompt that ranks issues by severity, explains the risk and keeps style nits in their place.

Review the following {{language}} code. It's part of {{what the system does}}
and will run in {{environment, e.g. a busy web API, a nightly batch job}}.

"""
{{code}}
"""

Review it like a kind but picky senior engineer. Organise your comments as:

1. MUST FIX: bugs, security problems, data loss, crashes. For each: the line,
   what could go wrong, and a concrete fix.
2. SHOULD FIX: missing tests, unclear names, error handling, performance traps.
3. NITS: style and preference. Maximum three.

Then:
- Name the single test you'd write first and show it.
- Tell me one thing the author did well, specifically.

If you're unsure whether something is a bug, say so and explain what
information would settle it. Do not invent APIs that aren't in the code.

The Pre-Mortem

Imagine the project already failed, then turn that story into ranked risks, warning signs and one cheap test.

It is {{date six months from now}}. Our project, {{project name}}, has failed.

Here's what the project is:
{{two or three sentences: goal, team, timeline, budget}}

1. Write a short, believable story (under 200 words) of how it failed,
   as told by someone on the team.
2. List the eight most likely causes of failure. For each, rate
   likelihood (1-5) and damage (1-5), and sort by likelihood x damage.
3. For the top three, give one early warning sign we'd see in the
   next 30 days.
4. Suggest the single cheapest test we could run this week to reduce
   the top risk.

Be specific to our situation. No generic risks like "poor communication"
unless you can say exactly how it would show up.

Quiz Me Until I Get It Wrong

An adaptive quiz that gets harder each time you're right and explains clearly when you're wrong.

Quiz me on {{topic}} at {{level, e.g. GCSE, first-year university, curious adult}}.

Stop when I say "done" and give me a short study plan for my weak spots.

Write the Hard Email

For emails you've been avoiding: declining, delivering bad news or asking for something awkward, kindly and clearly.

I need to write an email I've been putting off.

Recipient: {{who they are and our relationship}}
What I need to say: {{the hard message}}
What I want to happen next: {{desired outcome}}
What I'm worried about: {{the fear, e.g. sounding cold, damaging the relationship}}

Write three versions:
1. Direct: the message in the first two sentences, warm but brief.
2. Gentle: a little more context first, same clarity by the end.
3. Very short: five sentences maximum.

For every version:
- Never apologise more than once.
- No vague phrases like "moving forward" or "touch base".
- End with one clear, specific next step.

Then tell me which version you'd send and why, in one sentence.

Socratic Tutor, No Answers Allowed

A tutor that only asks questions and gives hints, so you build the understanding yourself.

Act as a Socratic tutor for {{subject}}. I'm working on this problem:

{{problem}}

Rules for you:
- Never give me the answer or write the solution for me.
- Ask one guiding question at a time.
- If I'm stuck twice in a row, give a small hint, not a step.
- If I make an error, ask a question that helps me notice it myself.
- When I reach the answer, ask me to explain why it works in my own words.

If I ask you to just tell me the answer, remind me of this deal and offer
a bigger hint instead.

The Friday Weekly Review

A 15-minute guided weekly review: what happened, what slipped, and what next week is really for.

Guide me through a 15-minute weekly review. Ask me one question at a time
and wait for my answer before moving on.

Questions to cover:
1. What did I finish this week? (Ask me to list, then celebrate one item specifically.)
2. What slipped, and was it the plan or the week that was wrong?
3. What's one thing I learned or would do differently?
4. Looking at next week's calendar ({{paste calendar or key commitments}}),
   what's the ONE outcome that would make it a good week?
5. What will I say no to next week to protect that outcome?

At the end, give me a five-line summary I can paste into my notes,
and one gentle observation about any pattern you noticed.

Ten Headlines, Three Angles

Generate headlines that come at a story from genuinely different angles, then pressure-test the best ones.

I'm writing a piece about {{topic}} for {{publication or audience}}.
The core point is: {{one-sentence summary}}.

Write ten headlines in three groups:
- Angle A, the news: what happened or what's new (3 headlines)
- Angle B, the reader: what it means for the person reading (4 headlines)
- Angle C, the surprise: the counterintuitive or human detail (3 headlines)

Constraints: under 12 words each, no colons, no questions, no "Here's why".
Avoid these words: game-changer, revolutionise, unlock, everything you need to know.

Then pick the two strongest overall and, for each, tell me:
- what promise it makes to the reader
- whether the piece as summarised actually keeps that promise

One Post, Five Formats

Repurpose one strong piece of content into five native formats without it feeling copy-pasted.

Here's a piece of content I made:

"""
{{original post, script or article}}
"""

Repurpose it into five formats, each native to its platform rather than a summary:
1. A short newsletter section (120 words) with a personal opening line.
2. A carousel of 6 slides: slide text only, one idea per slide.
3. A 45-second video script with a hook in the first three seconds.
4. A discussion question for a community forum that invites real replies.
5. A plain-text post under 280 characters.

For each one, change the angle slightly so someone who sees all five
isn't bored. Keep my voice: {{describe it in three words}}.
