You Need a Public Portfolio - MAC144

The day you find out your role is being eliminated is a terrible day to start building your reputation. So is the morning you finally decide you've earned a promotion — and you realize the only people who can speak to what you've actually done all sit inside the same building you're now trying to leave.

I want to talk about something almost nobody does until they're in crisis, which is exactly why so few people do it well: posting publicly. Putting your thinking, your work, and your expertise somewhere the world can actually see it. LinkedIn, a blog, a newsletter, a YouTube channel — it genuinely doesn't matter which.

And I already know the objection, because I've heard it from sharp, capable people for thirty years. "I'm not looking for a job. I'm happy where I am. Why would I bother?"

Here's what I want you to sit with. That feeling of security is not a reason to skip this. That feeling of security is the window. It's the one stretch of your career when you have the time and the calm to build the thing you'll be desperate for later. And most people sleep right through it.

The comfort trap.

Most people decide whether to post publicly based on a single question: am I job-hunting right now? If the answer is no, they don't post. If the answer is yes — if the layoff hits, or the promotion slips away — suddenly they're updating a profile that's been frozen for three years and scrambling to look like someone who's been engaged all along.

That's the wrong variable. Whether you're job-hunting today tells you nothing about whether you'll need a public track record tomorrow. And the timing of tomorrow is almost never yours to choose.

Think about how the actual disruptions arrive. The reorg you didn't see coming. The acquisition that quietly makes your whole team redundant. The new VP who brings their own people. The budget cut that lands in a quarter that looked fine in January. None of those put a note on your calendar. They show up, and the clock starts the same day — and that's the day you'd be starting from zero.

I've watched genuinely excellent people get caught flat-footed by this. Not because they weren't good at their jobs — they were often the best on the team. They were caught because everything they'd built was internal. The trust, the track record, the reputation — all of it lived inside one company's walls, legible to exactly the people who could no longer help them.

Paint the picture. A senior analyst, fifteen years at one company, universally respected inside the building. Everyone she works with knows exactly how good she is. Then the acquisition closes, her function gets consolidated, and she's in the market for the first time in over a decade. She opens her laptop to start reaching out — and discovers her network is almost entirely people at the company she just left, her LinkedIn hasn't been touched since she set it up, and when she searches her own name there is nothing there that says what she can actually do. Fifteen years of excellence, and from the outside she looks like she started yesterday. None of that was a competence problem. It was a visibility problem, and it was completely preventable on any ordinary Tuesday in those fifteen years.

So here's the reframe I want you to make. The question isn't "am I looking for a job." The question is "if the ground shifted under me next month, what could I point to that exists outside these four walls?" For most people, the honest answer is nothing. And that's a structural risk, not a personal failing — it's just the default state nobody warned you to fix.

The comfort isn't the problem. The comfort is the opportunity. You're just not supposed to waste it.

Internal wins versus external wins.

Let me get specific about what I'm actually asking you to build, because the right mental model changes everything. Draw a hard line between two kinds of wins.

An internal win is the project you shipped, the process you fixed, the fire you put out, the report you turned around over a weekend. It's real. It mattered. And it is almost completely invisible the moment you step outside your company. It lives in a Slack thread, a deck nobody kept, a manager's memory that fades the day they change jobs. Internal wins evaporate.

An external win is the same work — but made searchable. It's the short write-up of how you fixed that process, posted where anyone can read it. It's the breakdown of what that project taught you. It's the comment you left on an industry post that showed how you think. External wins are portable. They follow you. They're still working for you years after the project itself is forgotten.

The collection of those external wins, accumulated over time, is your public portfolio. Not a fancy personal website — though it can be. Just a body of public work that demonstrates, rather than claims, what you can do.

And I want to be precise about the difference between demonstrating and claiming, because it's the whole game. Your resume is a list of claims. "Strong communicator. Strategic thinker. Cross-functional leader." Everyone writes those words; they cost nothing to type. A public portfolio is evidence. It's the difference between telling someone you can teach and pointing to fifty things you've taught. One is cheap. The other is proof.

This matters even if you never leave.

Here's the part that lands hardest for the "I'm not looking" crowd. You don't have to leave for this to matter. The people deciding your promotion are evaluating you too — and increasingly, they're looking outside the building to do it. The data on this is not subtle. Roughly seventy percent of employers research candidates online before they make a decision, and more than eighty percent of hiring professionals screen someone's online presence before the interview even happens. And it doesn't stop at the hiring gate — that scrutiny continues throughout your time at a company.

Sit with what that means. When someone goes looking for you and finds nothing, that emptiness is not neutral. In a market where everyone else has something, a blank result is itself a signal — and not the one you want sending. I talked a few weeks back, in the episode on how AI is eroding the signals employers use to judge talent, about how the cheap, easy-to-fake markers have lost their meaning. A real, accumulated body of public work is the opposite of cheap. It's the costly signal that's hard to fake — which is exactly why it's worth so much.

Why the long game quietly rewards you.

A single post does almost nothing — let's be honest about that. But public work has a strange property: it keeps working after you've stopped. The developer and writer known as Swyx makes this case better than anyone in a piece on learning and building in public — durable work you put out keeps paying you back for years, long after you've moved on from it. The piece you wrote two years ago is still out there being found, still introducing you to people while you sleep.

That's the one place the word genuinely applies — your reputation compounds. Each piece sits on top of everything you've already published instead of starting over. Fifty posts isn't fifty times one post. It's a base that keeps generating return long after the effort is spent.

And notice what that means for the kind of person who's reading this: you do not need a single post to take off. The whole model rewards the boring, consistent middle far more than the occasional viral hit. Fifty-two ordinary posts over a year beat one brilliant post you agonized over and then never followed up. Consistency is the strategy that's actually available to a busy professional with a real job — you don't have to be clever or lucky on any given week, you just have to keep showing up in small, low-stakes increments. The person who posts a plain, useful paragraph every Friday for a year will, without exception, end up more findable and more credible than the person waiting for the perfect think-piece they never publish.

There's a name for the upside of all that visibility, and longtime listeners already know which quote I'm about to reach for. The Roman philosopher Seneca said that luck is what happens when preparation meets opportunity. I built one of my earliest episodes around that line — A Little Bit of Luck — and I've returned to it more times than I can count since, in everything from Reorganizations to Riding the Coattails of Others.

Here's the part most people miss in that quote. They fixate on the preparation — deliver results, build skills, earn credibility — and they ignore the opportunity half entirely. But opportunity has a precondition: you have to be visible to it. Preparation you keep to yourself never meets anything.

That's exactly what Harvard Business Review put research behind in a piece on how to create your own career luck: opportunity isn't random, it's roughly proportional to how findable you've made yourself. You cannot be pulled into the conversation you were never visible for. You can't be recommended for the role nobody knew you'd be good at. Every public thing you put out is another surface for luck to land on — another way for the right person to find you, remember you, and trust you before you ever ask them for anything. Posting publicly is just preparation made visible.

This isn't a new idea on the show. I've talked about Visibility, about your Personal Brand, about building a Leadership Portfolio, all the way back to Documenting Your Work. What's different now is the urgency and the venue. It's no longer enough for the documentation to live inside your company. The evidence has to exist where the world — and the algorithm — can find it.

The real reason you haven't started.

If the case is this clear, why don't more people do it? It isn't time. I've watched people who protect two hours for the gym every morning swear they can't find ten minutes to write something down.

The real blocker is quieter than that. It's the small voice that says: who am I to post anything? I'm not an expert. Everyone already knows this. I'll look like I'm showing off.

I want to name that directly, because it stops more careers' public presence than busyness ever will. It's a flavor of imposter syndrome, and the surveys put it at the majority of professionals, not the minority. You are not unusually unqualified. You are unusually normal.

So let me give you the reframe that gets people unstuck. Stop thinking of it as self-promotion. Think of it as value-sharing. Those are two completely different acts. Self-promotion is "look how great I am" — and yes, that feels gross, and you're right to recoil from it. Value-sharing is "here's something I figured out that might save you some pain." Nobody resents the second one. People are grateful for it. You're not bragging. You're teaching one person something you already know.

And that reframe also answers the "I have nothing to say" problem. You don't have to be the world's leading authority on anything. You only have to be a year or two ahead of someone else. The thing that feels obvious to you — the workaround, the lesson, the mistake you won't make twice — is genuinely valuable to the person who hasn't learned it yet. You're not writing for the experts above you. You're writing for the version of you from two years ago.

One practical bridge here. A few episodes back I talked about the brag document — the private running record of your wins. That private document is the raw material for your public output. You're not inventing things to post. You're taking what you already captured and translating one internal win into one external, shareable piece. The hard part — noticing what you did — is already done.

And on quality: the bar is lower than you think. The goal is not a polished essay you're proud of in a frame. The goal is a published one. The feedback, the connections, the luck — none of it starts until the thing is actually out in the world. Done and public beats perfect and private every single time.

Your action plan.

1. Pick one platform and one cadence — then stop deliberating. Don't build a website, a newsletter, a YouTube channel, and a blog all at once. Pick the single place your professional audience already is — for most people that's LinkedIn — and commit to one post a week. Not daily. Weekly. The platform matters far less than the consistency, and the fastest way to fail is to spend three weeks choosing tools instead of publishing.

1. Mine your own week for the first post. You already have material. Look at what you did this week — a problem you solved, a lesson you learned, a thing you wish you'd known earlier — and write it down for the person two years behind you. Three short paragraphs. That's a post.

1. Translate one internal win into an external one. This week, take a single thing that currently lives only inside your company and make a public, sanitized version of it. Strip out anything confidential, keep the general principle, and put it where it can be found. One win, moved from invisible to searchable.

1. Publish before you feel ready. Set a deadline — this Friday — and hit publish even though it's not perfect. The discomfort you feel is not a sign you're doing it wrong. It's the sign you're doing it at all. You can edit a published post; you cannot get anything back from a draft that never went out.

1. Audit what's already there. Google yourself the way a hiring manager would. See what comes up — including the nothing that comes up. That search result is your real first impression now, and you want to be the one deciding what it says.

The close.

The day you need a public track record is the worst possible day to begin building one. The portfolio that saves you — at the promotion table, in the layoff, in the move you didn't plan to make — is the one you started quietly, years earlier, when nothing was on fire and no one was making you.

That's the strange thing about this kind of work. It feels optional right up until the exact moment it isn't, and by then the window has closed. So you build it in the quiet. You plant the tree in the season you don't need the shade.

You don't have to go viral. You don't have to become a personality. You just have to be findable, consistently, by the people who'll one day go looking. Start this week. Your future self will not remember the post you were nervous about. Your future self will only wish you'd started sooner.

If this is landing, do one thing: share it with one person who needs to hear it, and find the show wherever you listen at managingacareer.com/follow. This podcast grows the same way your portfolio does — one person at a time, passed hand to hand by someone who found it useful.
