Work Fixtures

Engineering Your Way Into Deep Work

This essay is part of my Scale-Smart Moves series on tactics & operations that compound across your system. See the full index here.

If there is one thing I got right early in life, it’s deep work.

Almost everyone around me struggles with focus. I don’t. Never have. But I only recently understood why. It’s not discipline. Not willpower. Not even “good habits,” at least not in the usual sense.

It’s simpler: I almost never start a work session without a fixture.

In programming, a test fixture describes the setup that must exist before an automated test can run. A work fixture is the same idea applied to focus. It’s your ready state.

Deep work rarely fails because of weak character. It fails because of small misalignments: slight discomfort, vague scope, background noise, unfinished loose ends, and digital residue. A work fixture reduces friction and prunes zeigarniks before they start pulling on your attention. It helps you set up an environment that is favorable to “running” deep work.

Most people try to achieve that with a pre-session ritual. Fetch coffee, put on headphones, block the internet, close the door, then finally begin. That’s a good start. But here’s the twist that turns such a ritual into an actual fixture: Stop describing steps. Start describing the state. A ritual is choreography—always the exact same sequence of actions. A fixture is a more flexible checklist of conditions that lead to the overall optimal state.

So instead of:

1. Make coffee

2. Go to the bathroom

3. Close the door

You write down something like:

• Bladder empty

• Water nearby (200ml+)

• Coffee ready

• Door closed

The difference between a ritual and a work fixture lies not just in the wording. With a work fixture, you may meet the conditions in any order. Sometimes you will fetch coffee before hitting the restroom, sometimes the other way around. If you have a toddler, meetings, a weird day, whatever, a rigid sequence breaks easily. A state checklist is order-independent, so you can still “arrive” even if the path changes.

Now, what are some good conditions to include in a work fixture?

The most obvious condition is the scope of the work you are going to do:
What exactly will this session be about? What task are you going to tackle?

In my book, I call answering these questions assembling the Focus Scope (FOS). Setting one clear intention of what this work session will produce or progress. This doesn’t always involve writing something down — sometimes it’s a quiet resolution, sometimes it’s selecting the right artifact in your TAM, or writing a crisp line in your macOS menu bar. What matters is that you’ve decided on the intention before you enter The Forest.

Beyond scope, here’s what else to consider:

• Bladder empty

• Water nearby

• Coffee or tea ready

• Noise-canceling headphones on

• Focus music playing (e.g., Brain.fm).

• Calendar checked & clear for session duration

• Doors & Windows closed

• Lighting adjusted

• Desk tidy

• Body activated (e.g. few jumping jacks before sitting down)

• Breathing settled (A few slow breaths taken)

• Phone out of the room

• Notifications off / Do Not Disturb on

• Messaging apps muted

• Internet blocked

• Time tracker started

• Pomodoro session started

• Standing desk adjusted

• Walking pad ready

No individual condition can guarantee deep work on its own. But stacked together, they create something close: a reliable, ready state. The environment your best work runs on. A signal to your mind and body that this matters. That you’re entering focus now.

This is what makes work fixtures a scale-smart move.

1. A fixture is a smart default for your pre-session state — designed once, run implicitly every time. You don’t decide what conditions to meet before each session. The fixture already decided. You just show up and check the boxes.

2. A fixture contains fractalling cues: it makes you zoom out before the session — check the day, reduce surprise collisions — so you don’t keep negotiating with reality while you work. It makes you zoom in at the start — pin down the exact task — so the session has a spine. And it cocoons you from external noise during the session, so you stay locked at the right scale once you’re in.

3. A fixture scales across session types. Not every session needs the full fixture. Some days you don’t have the energy to go deep. Other days, the work doesn’t call for it. Apply a smaller fixture — same note, fewer conditions. Mark your non-negotiables: bold them, flag them with an emoji, whatever makes them visually distinct.

One setup. Multiple scales. That's the compounding advantage.

Here’s a challenge: write down your current work fixture (whether you chose it consciously or settled into it over time). Not as a ritual. As a checklist of conditions. Start with five. Ask: What must be true for your best sessions to happen?

I’m curious what you come up with. Drop it in the comments. 👇
