Build a Routine That Thinks for You


Hello Reader,

I used to block off time every morning to map my daily priorities—carefully listing, sizing, and prioritizing. But after a few weeks, I stopped thinking about it. The process ran itself. I’d open my laptop, coffee in hand, and start without hesitation.

That’s automaticity at work: when behavior becomes so embedded, your brain no longer “decides” to do it—it just does.

Automaticity is what happens when effortful repetition transforms into unconscious execution. It’s not just habit—it’s a kind of mental compression. Once a routine reaches this threshold, the brain offloads it from high-energy, deliberate thinking (System 2) into the low-power, fast lane (System 1). The result? More bandwidth for problems that actually require thought.

I’ve loaded 100 of the most valuable mental models into Re:Mind, a pocket-sized clarity toolkit for better thinking. We wrapped our Kickstarter with $8.4K in pledges, and both stretch goals were met. If you missed the campaign, late pledges are still open.

Why Use It

Understanding automaticity helps you use your cognitive resources strategically. It lets you:

  • Reserve mental energy for novel or complex challenges
  • Turn high-frequency tasks into invisible helpers
  • Recognize when a behavior is outdated, even if it feels “easy”

When to Use It

  • Daily planning rituals: Turn micro-decisions into scripts that run without friction.
  • Code linting and inbox triage: Automate rule-based tasks so they don’t drain attention.
  • Sales calls or onboarding flows: Embed routines into the flow to build consistency while reserving flexibility for edge cases.

How to Use It

In The Bourne Identity, there’s a moment where Jason Bourne is cornered in a café. Without hesitation, he scans for exits, disarms a police officer, and disables threats in seconds—all before the other characters fully process what’s happening. He doesn’t stop to think—his body executes a sequence he’s rehearsed a thousand times. While we’re not dodging assassins, the same principle applies: with enough focused repetition, even complex actions can become lightning-fast, unconscious responses.

Here’s how to build healthy automaticity:

  • Deliberate focus up front: Practice slowly and correctly—your brain records what you repeat, errors included.
  • Spaced repetition: Spread practice over time; cramming doesn’t stick.
  • Environmental triggers: Use consistent cues so your habit starts without debate.
  • Periodic audits: Calendar “habit reviews” to check if your autopilot is still taking you somewhere you want to go.
  • Progressive overload: Layer in new complexity once basic steps are baked in.

Next Steps

Automaticity is about freeing mental RAM—but it’s not a set-and-forget system. Begin by spotting repeated micro-decisions in your day. Script them. Tie new habits to clear cues. And occasionally, pause to ask: Is this still serving me—or just running in the background because it can?

Where It Came From

The concept of automaticity is rooted in cognitive psychology and skill acquisition research. One of the earliest formal models comes from Fitts and Posner, who described skill development in three stages: cognitive (effortful and conscious), associative (refined through practice), and autonomous (fast and unconscious).

Psychologist John Bargh expanded the idea with four key characteristics of automatic behavior: low awareness, lack of intentionality, high efficiency, and reduced controllability. This explains why we can drive familiar routes or read fluently without consciously thinking through each step.

Whether on the road (as in “highway hypnosis”) or in high-stakes performance, automaticity frees the mind to focus on what’s novel—so long as we keep tuning what runs in the background.

Until next time, keep exploring and questioning. Your unique perspective is your greatest asset.

Hello Reader, A few weeks ago, I blocked off a Saturday to work on some core updates to the Re:Mind deck. No meetings. No email. Just headphones and focus. And I got more done in four hours than I had in the previous four days. That’s the power of Deep Work—extended periods of distraction-free focus where real progress gets made. Deep Work creates the conditions for clarity, flow, and original thinking. When we protect our attention, we recover our best ideas. I’ve loaded 100 of the most...

Hello Reader, A few weeks ago, I was about to simplify an onboarding step in my app that felt clunky—an extra screen no one needed. I was ready to cut it to speed things up. But before I scrapped it, I paused. Why was it there in the first place? Turns out that step wasn’t just friction. It included an authentication check that helped prevent drop-off and improved conversions. Removing it would have quietly broken the system. That’s Chesterton’s Fence in action: don’t remove a fence until you...

Hello Reader, Earlier this year, I launched an ad campaign and watched clickthrough rates rise—but conversions didn’t budge. My gut said it was working. The data said otherwise. That tension between intuition and analysis? That’s the heart of fast and slow thinking. Fast and Slow Thinking is the dual-system model of decision-making introduced by Daniel Kahneman. System 1 is fast, intuitive, and automatic. It helps us recognize faces, finish sentences, and react to threats. System 2 is slow,...
