What efficiency means to me
Efficiency sounds cold. Robotic. Like optimizing every moment of life for throughput, squeezing joy out of anything that doesn't produce output.
That's not what I mean.
Efficiency, to me, isn't "do more in less time." It's something deeper: almost every other value, when you trace it back far enough, turns out to be efficiency in some form.
Quality
Quality seems like the opposite of efficiency. Take shortcuts, ship fast, cut corners - that's efficient. Quality takes time.
But quality is efficiency. A well-built thing breaks less often. It requires fewer fixes, fewer workarounds, less support. A well-written document gets read once and understood. A well-designed system gets extended without pain. Quality pays for itself - and then some.
Speed
Speed is the obvious one. Going faster means getting more done. But speed without direction is just spinning wheels. True efficiency isn't about moving fast - it's about moving fast in the right direction . Speed is a tool, not a goal.
Features
More features can mean more value - but only if they solve real problems. A bloated product with fifty features nobody uses isn't efficient. The right features, working well, is.
Unix got this right decades ago: do one thing and do it well. But the principle extends far beyond software. A specialist who is truly excellent at one thing is more valuable than a generalist who is average at ten. A restaurant with a short menu of dishes done perfectly beats the one with forty options done mediocrely. Focus is a feature.
Simplicity
Related to focus, but broader: everything you carry has a cost. Possessions need maintaining. Commitments need honoring. Options need evaluating. The more you accumulate - things, obligations, complexity - the more of your attention goes to managing it all instead of the things that actually matter.
Simplicity isn't about having less for its own sake. It's about not carrying weight that doesn't earn its place.
Teaching others
Teaching feels slow. You invest time in someone else's growth instead of doing the work yourself. But teaching is one of the highest-leverage things you can do. You multiply your knowledge across every person you teach. The short-term cost is far outweighed by the long-term return.
Reading
A book is a compressed version of someone else's years of experience. One good book can save you from mistakes that would otherwise take a decade to make yourself.
Reading is one of the highest-return investments of time that exists. Not all reading - but the right book, at the right moment, can change the trajectory of how you think.
Saying no
Every yes is a no to something else. Saying no to low-value requests isn't unhelpfulness - it's protecting the finite attention and energy you have for things that actually matter.
This applies everywhere: the commitment you take on out of obligation, the invitation you accept but dread, the project you say yes to when you're already stretched. The ability to say no clearly and without guilt is one of the most underrated efficiency skills in life.
Clear communication
A misunderstanding avoided is a long conversation you never had to have. A message that lands clearly the first time is faster than a short one that sparks three rounds of back-and-forth.
This applies at work, at home, in friendships. Investing in clarity - saying what you mean, asking the right question, being explicit about what you need - pays back every time.
But clear communication doesn't start when you need it. It's built long before - through knowing each other. Knowing how someone thinks, what they care about, where their instincts take them. That shared understanding is what lets a single sentence do the work of a paragraph.
Every conversation about nothing in particular is quietly building that model. The chat about weekend plans, the tangent about a book, the opinion shared over coffee - none of it feels useful in the moment. But when time is short and clarity is everything, you draw on exactly that. You already know how they'll hear it. You already know what they need to understand.
Inspiration and play
This one surprises people. How is inspiration efficient?
Because without it, you eventually stop moving. You grind through work you don't believe in. You produce average output with decreasing motivation. Inspiration refuels you - it unlocks energy you wouldn't have found otherwise. Seeking it isn't wasteful. It's maintenance.
But inspiration rarely comes from doing more of the same thing. It comes from the detour - the hobby that has nothing to do with your job, the book outside your field, the weekend spent painting. These feed you in two distinct ways.
The first is active: cross-domain thinking. How does painting make you a better engineer? It teaches you to see structure in chaos - to notice composition, balance, what to leave out. It trains patience with iteration: a painting is never done in one pass, and neither is good software. It gives you a relationship with imperfection that's different from the one you have at work, where mistakes have consequences. On the canvas, a mistake is just the next decision. That looseness, brought back to the keyboard, changes how you approach problems. The skill doesn't transfer. The thinking does.
The second is passive: the restoration that comes from a mind not trying. The relaxed evening with no agenda, the weekend trip, the hobby you lose track of time in - these aren't escapes from real life. They access something that focused, optimized effort can't produce on its own. Insight often arrives not when you're pushing for it, but in the gap after you've stopped.
Health
Your body is the substrate everything else runs on. If it's breaking down, everything else gets harder - you think slower, recover less, have less to give.
Exercise, nutrition, rest, regular checkups - these feel like interruptions to productive time. They're not. They're the maintenance that makes everything else sustainable. Neglecting health looks like saved time, right up until it costs much more.
Sleep
Eight hours doing nothing. Surely that's the least efficient thing imaginable.
It isn't. Sleep is when the mind consolidates what it learned, clears what it accumulated, and restores the capacity to think clearly. A well-rested person makes better decisions faster, stays patient longer, and handles setbacks with more perspective. Sleep isn't downtime. It's what makes the uptime worthwhile.
Social and psychological wellbeing
Stress, loneliness, and unresolved emotional weight don't stay in their lane. They leak into everything - your focus, your creativity, your patience with the people you love, your judgment under pressure.
Investing in relationships - having a family, building real friendships, maintaining them - and in whatever keeps you psychologically well isn't a soft extra. It's a prerequisite for showing up fully in every other area of life.
Coffee chats and social interactions
The hallway conversation feels like lost time. Ten minutes with a neighbour about nothing in particular. A chat that drifts from the weather to childhood to something you'd never have thought to bring up. Nothing "got done."
But those conversations are how you actually know people. Not their job title or their opinion on the topic at hand - how they think, what they find funny, what they care about when there's no agenda. That kind of knowing is slow to build and impossible to shortcut. And it's exactly what makes everything else easier: the hard conversation, the favour asked, the moment when you need someone to just understand without a lot of explanation.
Habits and routines
Every decision costs something - a small draw on attention and willpower. A habit is a decision you made once and never have to make again. Morning routines, exercise schedules, a regular evening rhythm - they remove the overhead of choosing from things that don't deserve that overhead.
The goal isn't rigidity. It's freeing up attention for the things that actually require it.
And much else besides
The same logic applies to things I haven't covered individually here. Financial stability isn't wealth - it's margin: the room to say no to bad opportunities and not spend mental energy on survival. A home-cooked meal takes longer than fast food but returns more in nutrition, energy, and satisfaction. Experiences - the trip, the challenge, the season of life fully shown up for - aren't detours. They're investments in the person doing all the other work.
You could trace this through almost anything. What you own, how you structure your evenings, which commitments you keep. The efficiency question is usually underneath, whether you name it or not.
Prevention
There's a pattern running through everything above: small measures now prevent larger problems later. That's not just a side effect - it's one of the highest-leverage forms of efficiency there is.
Exercise doesn't just make you healthier. It prevents the years of decline that follow from not exercising. Sleep doesn't just restore you. It prevents the compounding cognitive debt of running on empty. Relationships don't just enrich your life. They prevent the isolation that makes hard times unbearable. Good code doesn't just work. It prevents the rewrites, the incidents, the months lost to a system nobody understands.
Prophylaxis scales. The smaller the measure, the earlier it's taken, the more damage it forestalls. A difficult conversation had now is a crisis avoided later. A habit built in your twenties is a decade of defaults you never have to fight. A maintenance checkup is not a cost - it's insurance against something far more expensive.
The inefficient path is always the one that skips prevention and pays full price downstream. The efficient one invests a little, consistently, before it's urgent.
Efficiency, when I say it, isn't a cold metric. It's a framework for understanding value over time. It asks: what does this give back, and when?
Most things that seem inefficient are just deferred efficiency. And most things that seem efficient in the short term are just deferred costs .
That's why efficiency is my north star - not because I want to squeeze every second dry, but because I want to spend my time on things that actually matter.
