The Rules You Never Chose: Who Made Them Up

Three and a half years ago, I cut my workweek to three and a half days. The logistics were the easy part: rearranging my calendar, telling clients. The part that stayed with me came on a quiet Tuesday morning, when I realized the five-day week I had organized my entire adult life around was a number a car company picked in 1926.

Henry Ford gave his workers Saturday and Sunday off that year, and his stated reason was sales. A man stuck on the factory floor from dawn to dusk had no time to drive, and so no reason to buy, a car. In Ford's own published words, "The people who consume the bulk of goods are the people who make them." I had spent two decades treating one industrialist's consumer-economy strategy as the natural shape of a working life.

Once you see one of these, you start seeing them everywhere.

Most rules we organize our lives around were invented by a specific person, for a narrow reason, then handed down as if they were physics. The five-day week came from a 1926 car-sales plan. Naming a rule as something somebody made up turns a default you tolerate into a choice you get to make.

The rules we treat as gravity

Take the rest of that workweek apart and it keeps coming undone. The eight hours inside the day started as a slogan a mill owner named Robert Owen coined back in 1817. The 40 itself became United States law through a 1938 statute that made hours past a weekly line expensive, and that line did not even settle at 40 until 1940. We spent the better part of a century treating a payroll accounting threshold as a measure of how long a human being works well.

Retirement at 65 has the same shape. When the United States built Social Security in 1935, a committee settled on 65 as the retirement age, drawing on a blend of actuarial math and the pension precedents already floating around. You can read the reasoning on the Social Security Administration's own history page. A reasonable estimate made by a New Deal committee now tells hundreds of millions of people the exact decade their working life is supposed to end.

The number your doctor reads off a chart has a similar origin. Body mass index came from Adolphe Quetelet in the 1830s. He was an astronomer and statistician studying populations, and he said plainly that his formula described groups of people and was never built to judge a single body. The phrase "body mass index" did not exist until a researcher attached it in 1972. A tool for counting crowds became a verdict on your individual health.

Then there is the three-digit number that decides whether a stranger trusts you with a mortgage. An engineer named Bill Fair and a mathematician named Earl Isaac started their company in 1956, and the general-purpose FICO score launched in 1989. A private formula, owned by a company, now functions as a measure of your personal trustworthiness.

Here is the part that matters more than the trivia. Every one of these came from a real person doing their best with what they knew. None of them set out to define your life. Quetelet was describing populations; Ford was selling cars. They each solved the problem in front of them, well, and we inherited the answer and forgot it had an author.

Why nobody fixes a rule that mostly works

A made-up rule survives for one quiet reason: it is tolerable. A tolerable rule never climbs to the top of anyone's list to redesign, so it sits there for a century, collecting the authority of age. Tolerable is the enemy of sovereignty.

I watch this in the CTOs I coach, some of the sharpest operators I have ever met. They will re-architect an entire engineering org over a single bottleneck, then never once ask why the workday is supposed to start at nine. The rule feels like weather. You plan around weather. You do not negotiate with it.

The people who built these systems are rarely the ones who update them, because they are inside the thing and wired to its incentives. The annual review keeps running because the people whose status depends on the annual review are the ones reviewing it. The lifetime-employment ideal those structures were built to reward already describes almost no one; median job tenure was 3.9 years in early 2024, the lowest since 2002. The scaffolding outlived the world it was built for, and we kept climbing it anyway. What you are not changing, you are choosing, and most of us are choosing things we have never examined.

When you know better, you do better

Maya Angelou gave us the line that fits this exact moment: when you know better, you do better. The old rules encoded what their makers knew. We just know more now.

This is where the current technology shift earns its keep. AI handed us new capability, and underneath the capability, a mirror. When a machine can draft the memo and book the travel, the scaffolding we built around being busy suddenly shows up as a set of choices instead of a set of facts. The work you assumed was the job turns out to be a habit you can question.

Seeing a rule as something somebody invented changes what it means to do it differently. It stops being rebellion and becomes integrity. You are declining to run someone else's 1926 sales plan on your one and only Tuesday.

The leaders this moment is waiting for

We keep waiting for the people who built these systems to fix them. They rarely can. So the leaders this moment needs are somewhere else, and a lot of them have not yet noticed it is their turn.

That recognition is the whole job of a threshold guardian: seeing someone's readiness and reflecting it back before they can see it themselves. Most people are standing at a doorway they keep mistaking for a wall. They have outgrown the inherited rule and assume the problem is them. The work is to name the doorway out loud, so the person can walk through a thing they had been bracing against.

You have three ways to live with a rule you never chose. The first is to play the game as it was handed to you, which is what most capable people do for most of their careers, and it works until the day it quietly stops fitting. The second is to build a game of your own off to the side. The third, and the one this moment is asking for, is to pick up the pen and author the rules so the game finally fits the person you have become. The people who built the old systems still referee their own game. The leaders this moment is waiting for are the ones reaching for the pen.

How to audit a rule you never chose

You do not need a framework for this. You need an hour and one rule you have been treating as fixed. Here is the audit I walk clients through.

1. Pick the rule. Name one convention you organize your life around without thinking, like the nine-to-five or the annual raise. Choose the one that made your jaw tighten as you read this, because the tightening is the signal.
2. Find the author. Ask who decided this, and for what narrow reason. The answer is almost always a company or a committee solving a problem that was never yours. The rule shrinks the moment it has a name and a date attached.
3. Feel the trade honestly. Name what the rule costs you and what it still buys you. Do the body check while you do the math. Where do you feel the rule? For me, the cost of a yes I do not mean shows up as a tight band under my collarbone, weeks before my calendar admits anything is wrong.
4. Redesign one thing. Not the whole system. One hinge. Little hinges swing big doors, as John Maxwell put it, and authoring your life starts with a single rule you decide to rewrite this quarter.

The first rule is the hard one. After that, the seeing compounds. You start catching the invented inside the inevitable everywhere, and the catching feels less like cynicism and more like waking up in your own life.

The five-day week was one man's plan for selling cars, and I get to decide whether it still runs my Tuesdays. So do you, on every rule you have been carrying since before you could question it. The fractional path I eventually built for myself started with this one question, asked once and then impossible to un-ask.

Which rule have you been treating as gravity, and who actually made it up?
