The honest test: tiredness is cured by resting

Let's start with the distinction that orders everything else. Tiredness is an energy debt: you sleep, you unplug for a few days, and on Monday — thrilled or not — you come back whole. It's the healthy fatigue of having worked. Depletion is something else, and it has one unmistakable signature: rest doesn't repair it. You come back from vacation and within two days you're exactly where you left off. You sleep ten hours and wake up with no charge. The weekend doesn't recharge: it only postpones.

That's the test you owe yourself: if resting works, it was tiredness — mind your rhythm and carry on. If resting has stopped working, stop increasing the dose of rest and expecting a different result. The problem isn't your battery. It's that something in there is draining it faster than any night can fill it.

What truly drains you (it isn't working hard)

I've spent three decades inside companies, watching brilliant people go out — and people carrying enormous loads light up. The amount of work is almost never the variable. These three are.

Effort without meaning. Working hard doesn't burn you. Working for nothing does. Reports nobody reads, meetings that decide nothing, projects cancelled in silence. Human effort needs to land on something that matters — however small — and when it never lands, the machinery starts spinning empty. And spinning empty wears you down more than spinning under load.

No command over what's yours. What you do, how you do it, when you do it: when all three answers always come from outside, something withers. It isn't a whim — it's how we're built. A person with no margin of decision over their own day becomes a passenger of their working life, and passengers don't get tired of the journey: they get tired of never driving.

Performing someone you're not, eight hours a day. Smiling at people you don't respect, defending what you don't believe, fitting into a culture that asks you to be someone else. Acting has an enormous, silent energy cost — ask any actor how they feel after a show. If your workday is a performance, the exhaustion doesn't come from the work: it comes from the character.

The trap underneath: when you are your job

There's an aggravating factor that turns all of the above into an identity crisis: having let work become the only source of who you are. It's an elegant trap — it dresses up as vocation, as commitment, as "but I love what I do" — and it works beautifully while work goes well. But concentrating your entire worth in a single source is building with a single point of failure: when work goes wrong, it isn't your calendar that goes wrong. It's you.

The signs that you're there: they ask who you are and you answer what you do. You imagine yourself without the title and feel vertigo, not curiosity. Achievements outside work — yours, your family's — feel second-rate. If you recognize yourself, write this down: diversifying the sources of your identity is not lowering your ambition. It's basic engineering. No engineer hangs a bridge from a single cable.

What to do — no privileged advice

I'm not going to tell you "quit and follow your passion." That advice comes from people who've already paid off their mortgage. What follows works inside a real life, with bills.

First, the diagnosis in writing: is it the work, or is it this job? Your profession being worn out is not the same as this place, this boss, this stage wearing you out. Paper, three columns: what drains me — what still fills me — what I'd change if I could. Be concrete: "the Monday meetings," not "everything." Very often you discover the problem has a first and last name, and that changes everything — because the concrete can be negotiated, dodged, or walked away from. "Everything" can't.

Second, take back an inch of command. You don't need total control — you need something of your own. How you organize your first hour. A project of yours, however tiny, that nobody asked for. A well-placed no. Command is recovered inch by inch, and the first inch changes the passenger feeling the most.

Third, light something up outside before deciding about the inside. Work drains the most when it's the only thing lit — all the pressure falls on a single bulb. Something small, regular, and ideally useless: something that produces nothing, that can't go on any résumé. Swimming, a vegetable patch, an instrument badly played. It isn't escapism: it's spreading the weight of who you are across more than one cable.

And fourth: if after all this the answer is "it's this place" — then you no longer have a state: you have a decision. And decisions have their own guide in this house: deciding with the fear inside — paralysis also decides, the reversible doors, the default date. It's waiting for you there.

When it's more than work

One more thing, looking you in the eye: if the Sunday dread is also there on Tuesday, and on Saturday, and in August; if nothing from anywhere — not even the outside things — lights up; if sleep never rests and everything has been heavy for months, then maybe work isn't the cause: it's just where it shows the most. That isn't solved by changing jobs, and you don't have to figure it out alone: psychotherapy, as the serious tool it is, is where that gets looked at properly.

For everything else: the three-column paper, the inch of command, the bulb outside. And one last idea to keep: work can fill your calendar — that's its place. What it cannot fill is the entire definition of who you are. Sunday evenings, looked at properly, aren't the problem. They're the warning. Listen to it before it has to shout.
