Where we start
The running case is still Ines Calloway, a constructed mid-career data analyst who forecasts demand for a regional grocery chain. She is invented for teaching, and everything she makes tonight is constructed; your work and your results will differ. Her session 1 audit found two of ten results that were hers and none that showed her work. Her session 2 line promised grocery planners forecasts they can check. Tonight she makes the first thing a stranger can actually check.
★ What you walk out with tonight. One finished piece of your work, checked for anything confidential, written up as a four-part teardown with an artefact a stranger can open, a title that carries your name, a place on a profile you keep, a one-card description of your voice, and a written cadence for the next twelve weeks that session 4 will put on a bench.
A claim is a promise; proof is a thing you can open
6 min liveEvery bio is full of claims, and a stranger cannot check any of them. The difference between a reputation and a self-description is what the reader can verify without asking you. The proof ladder is a working framework for that difference: four rungs, each asking the reader to take one less thing on trust.
LiveThe four rungs3 min▶
Rung 1, the claim. "I am good at forecasting." An adjective about yourself. It costs nothing to write, so it carries no information; everyone in your field can type the same sentence. Most profiles live entirely on this rung.
Rung 2, the description. "I built a forecasting model." Better: it names a thing that happened. But the reader still has only your word for it, and cannot tell whether the model was good, whether you built it or sat near it, or what you learned.
Rung 3, the artefact a stranger can open. A public teardown, a notebook on public data, a talk recording, a worked example. The reader can open it and judge the reasoning for themselves. This is the first rung that works when you are not there to explain, which is the whole point of a reputation.
Rung 4, the artefact someone else used. Somebody linked it, cited it, reused the method, or asked you about it in public. You cannot build this rung directly; it is what rung 3 earns over time. That is why the build-along aims at rung 3 and lets rung 4 follow.
Self-studyConfidential work: show the method, never the data3 min▶
Most of your best work belongs to an employer or a client, and the professional norm is simple: never publish their data, their numbers, their client names or anything a reader could trace back to them. That includes screenshots with the axis labels cropped, "anonymised" figures that are still recognisable, and the name of the client in a caption. If you would not show it to a competitor, do not show it to the internet.
What is yours is the method: the reasoning, the mistake you caught, the approach that fixed it. Rebuild that on public data or on a small toy example you make up, and say plainly that you did: "rebuilt on public data; the original was internal work". The rebuild is honest, it is shareable, and it often teaches better than the original because you strip it to the part that matters. When in doubt, ask whoever owns the work before you publish, in writing.
Two portfolios for the same job. One lists tools: a row of logos for languages, libraries and dashboards, and a line saying "experienced in forecasting". The other has one link: a finished teardown of a forecast that went wrong, what the analyst tried first, why it failed, and the chart that fixed it. The first asks a hiring manager to believe; the second lets them check in five minutes. The tool list sits on rung 1 however long it is. One teardown sits on rung 3.
Show the process, not just the product
6 min liveAustin Kleon's short book Show Your Work! (Workman, 2014) is the clearest map of how sharing process works in practice, and its ten chapter titles read as a checklist on their own. We list the titles only, as they appear on his site, and work out what each asks of you; the prose of the book is his to read, not ours to quote.
LiveThe ten titles, and what each asks of you4 min▶
The chapter titles, as listed on austinkleon.com. The second half of each line is our reading of what the title asks of a working professional, not Kleon's text.
- You don't have to be a genius. You do not need to be the leading expert to share; being a careful practitioner who is still learning is enough to start.
- Think process, not product. The steps, drafts and dead ends are shareable long before the finished thing is.
- Share something small every day. A habit of small, regular pieces instead of waiting for a big reveal.
- Open up your cabinet of curiosities. Share what you read and learn from, with credit, not only what you make.
- Tell good stories. Frame work as problem, attempt, result, so a stranger can follow it.
- Teach what you know. Explaining a method gives it away and makes you the person who explained it.
- Don't turn into human spam. Read, reply and help as much as you broadcast; the figure above draws the leak.
- Learn to take a punch. Public work draws criticism; separate the useful correction from the noise.
- Sell out. It is fine to say plainly what you offer, once the work has earned attention.
- Stick around. Reputations are built over years, not launches; session 6 comes back to this one.
Self-study"Share something small every day" is a habit, not a growth claim2 min▶
The third title is the one that gets lifted out of context. Read with its neighbours, it is advice about a working habit: get your process out of your head in small pieces, often, so showing your work stops being an event. It is not a measurement. The title does not say that posting every day grows an audience, and a chapter title could not show that even if it did.
Whether a higher cadence actually buys more engagement is an empirical question with an answer you can count, not a matter of who said it with more confidence. Session 4 tests it on real public data. Until then, treat "share something small every day" as a way to make sharing routine, and keep the separate question of what cadence earns open.
A common pattern in any professional feed: an account that posts every day and never replies to a comment, never credits a source, never asks a question. The volume is high and the loop is broken, because nothing the readers say ever reaches the work. A quieter account that answers every reply and links what it learned from is running the loop Kleon's titles describe. Ines (constructed) notices she has been the first kind on the rare days she posts at all: announcements, no conversation.
Voice is a set of choices you repeat
5 min liveAsk people to describe their voice and you get adjectives: warm, direct, authentic. Adjectives cannot be checked, and they cannot be followed on a tired Tuesday. A voice a reader can recognise is a small set of decisions you make the same way every time. Name the decisions and the voice becomes something you can keep.
LiveFive choices that make a voice3 min▶
1 · Who you write as. "I" for what you did, "we" only for what a team did, and never "we" to blur who did what. Readers looking for a person want to know which part was yours.
2 · How you hedge. Hedging everything sounds unsure; hedging nothing sounds like a sales page. Put one hedge exactly where your evidence runs out, and state the rest plainly. A hedge in the right place is a signal of honesty, not weakness.
3 · How much jargon. Decide who you write for and use their words. For grocery planners, "line years up by holiday" beats "temporal alignment". Keep a term of art only when the reader would search for it.
4 · The claims you never make. Write down two or three: no result without a number or a link, no "thought leader", no "world-class". A short list of refusals shapes a voice faster than a long list of aspirations.
5 · How you credit others. By name, specifically, every time the idea was not wholly yours. It costs one clause and it is the single most trusted signal on a page about your own work.
Length and format are choices too; pick a length you can sustain and keep it. Writing craft itself, sentence by sentence, lives in the communication course, and drafting, repurposing and AI writing tools live in the AI content course. Here the point is narrower: decide the five, so that every piece sounds like the same person.
Self-studyWrite down your voice in one card3 min▶
Take your three best pieces of writing, anything public or private you were proud of. For each of the five choices, write what you actually did, not what you wish you did. Where the three disagree, pick one and make it the rule. The result fits on an index card and you check every new piece against it before you publish.
Your card will differ. If a line on yours reads like an adjective ("friendly", "bold"), rewrite it as a decision someone could check.
A team handbook that says "our tone is friendly and professional" produces writing that varies by whoever wrote it, because nobody can apply an adjective. A handbook that says "we write in the first person, we name the person who found the bug, we never say a fix is permanent" produces writing that sounds like one place, because each line is a test you can run on a draft.
One piece of work, made public
★ 22 min · everyone buildsSix steps that take one finished piece of your real work from private to findable, with Ines's constructed teardown alongside as the worked example. Work in a plain document. You will not publish in the room; you leave with a draft that is ready to publish and a place to put it.
Choose the piece. Finished, not in progress; small enough to explain in one page; and something where you made a decision a stranger could judge. A mistake you caught and fixed is usually better material than a success, because the reasoning is visible. Pick the one closest to the promise in your session 2 line.
Run the confidentiality check. Go line by line through what you plan to show. Anything that belongs to an employer or client comes out: data, figures, names, internal tool names, screenshots. What is left is your method. If you are unsure about any line, it comes out, or you ask the owner in writing first.
Draft the four-part teardown. Problem, first attempt and why it failed, what worked, what you would do next. The failed attempt is the part readers learn most from and the part most people leave out. Keep each part to a short paragraph, in the voice card from Part 3.
Make the artefact. One thing a stranger can open: a chart with its data source named, a notebook that runs on public data, or a worked example small enough to do by hand. This is what lifts the teardown from rung 2 to rung 3. If you rebuilt on public data, link the source; if you used a toy example, say it is a toy.
Title it and place it. Put your name in the page title, because the page titles that tend to surface for a name search are the ones that carry it. Publish on a page you keep, ideally ground you own, and link it from the profile you actually maintain. That link is what lets a search engine connect the work to you.
Plan a cadence for the next twelve weeks. Write down how often you intend to publish something, of what kind, and how many teardowns that adds up to. Make it a number, not a mood. Ines (constructed) plans five posts a week: one teardown a fortnight and short process notes in between. That is her plan, written down so it can be tested, not a recommendation. Session 4 puts that plan on a bench.
Save the draft as teardown-1_YYYY-MM-DD, with the voice card and the cadence on the last page. When it is live, add its address to your session 1 audit sheet as the result you expect to see there in session 6.
Before session 4
60 min- Publish the teardown. Run the step 2 checklist once more on the final version, then put it live with your name in the title and link it from your profile.
- Climb your bio one rung. Find the strongest claim in your current profile and replace it with a link to the teardown, so the sentence moves from rung 1 to rung 3.
- Run the loop once. Share one small piece of process from the teardown, then reply to every response it gets and comment usefully on two other people's work. Note what came back.
- Bring the cadence you planned to session 4, as a number of posts a week, written down before you see any data.
Three questions
Clear all three and session 3 gets stamped in your passport.
1 · Ines (constructed) publishes a notebook on public retail data that anyone can open and rerun, showing how she lined up holiday weeks. Nobody has cited it yet. Which rung of the proof ladder is it on?
The test is what a stranger can check. They can open and rerun the notebook, so it is rung 3. Rung 4 needs someone else to have used, cited or linked it, which has not happened yet.
2 · Your best piece of work is an internal forecast for your employer. What can you publish?
The data, figures and names belong to the employer, and blurring or cropping does not change that. The method is yours to show; rebuilding it on public data and saying so keeps it honest and shareable. C throws away your best material for no reason.
3 · A colleague says "Kleon's book proves you have to post every day to grow an audience". What is the accurate reply?
A title can give advice; it cannot measure an effect. Whether cadence grows engagement is a separate, empirical question, and session 4 tests it on real public data. C invents advice the titles do not give.
