Computes Only What Matters
I have been quiet here lately. Between finalizing the manuscript for The Rational Optimist, drafting the early chapters of a new novel, and laying the groundwork for Atlas, a Korean typesetting engine, my bandwidth has been fully occupied. I had assumed I would leave this journal untouched for a while.
Yet, a specific thought recently crystallized in my mind. It was too clear to ignore, so I am logging it here. It is a single line that I have decided to adopt as my core operating principle:
Computes only what matters.
In computer science, a well-designed system does not waste CPU cycles on irrelevant data. It filters out the noise. It avoids memory leaks and over-engineering. It allocates its resources strictly to the logic that drives the final output. I realized recently that this is precisely how a rational mind should navigate a chaotic world.
We live in a reality flooded with unnecessary inputs. To maintain equilibrium, we must learn to drop the redundant packets. This principle applies far beyond the screen.
In building systems and pursuing work, I see the constant temptation of complexity. We often want to build features for problems that do not exist yet. But true elegance lies in subtraction. A robust architecture is not one that does everything; it is one that flawlessly executes the essential. Computes only what matters means resisting the bloat. Build the core, solve the actual problem, and leave the rest.
In the network of human relationships, our emotional bandwidth is finite. We frequently drain our energy dealing with emotional latency—arguing over misunderstandings, reacting to negativity, or worrying about the opinions of those who do not truly affect our lives. Applying this principle means setting a firewall against that noise. It is not about being cold or indifferent. It is about preserving my processing power for the nodes in my network that actually sustain me: my family, my close friends, and those who share a mutual respect.
In the realm of parenting, the noise is perhaps the loudest. There is an endless stream of unsolicited advice, societal expectations, and the inevitable, daily chaos of raising a child. If a father tries to process all of it, his system will crash. So, I choose to compute only the vital data: the steady rhythm of my child’s breathing, the slow, beautiful boot sequence of their consciousness, and the undeniable fact of our connection. The messy room or the minor mistakes? They are just background static.
In art and photography, we face a similar choice. It is easy to be distracted by vanity—the maximum aperture of a lens, the rarity of a brass barrel, or the theoretical sharpness on a spec sheet. But when I look through the viewfinder, none of that matters. The only metric of value is whether the tool allows me to step closer to my subject and capture the truth of the moment. If it serves the vision, it is useful. If not, it is discarded.
The universe naturally drifts toward entropy. Disorder is its default state. If we try to process every variable the world throws at us, we will lose our balance.
To live a life of equilibrium—built on reason and warmed by the heart—we cannot afford to compute everything. We must be fiercely selective. By computing only what matters, we protect our capacity for the things that make life profound: clear logic, deep focus, quiet creation, and enduring love.
This is the code I choose to run.
