The Person Behind It
Hey, I'm Domenic.
I've spent years collecting tools, frameworks, and mental models that actually work — most of them taught to me by mentors, refined through trial and error, and kept in notebooks for far too long. The Codex is what happens when you finally stop hoarding and start sharing.
The Origin
Not invented here.
Collected, tested, and shared.
co·dex /ˈkōˌdeks/ · noun
A A was the world's first bound book — pages stitched together, replacing the scroll. The Romans used them to collect laws, treaties, and knowledge worth keeping. Leonardo da Vinci filled codices with everything he was learning. The Vatican still holds them.
The name isn't accidental. This is the same idea — a bound collection of knowledge worth keeping — rebuilt for how people actually live and think today.
None of this is mine originally. It comes from mentors who took the time to show me how they actually think, books that reframed problems I didn't know I had, frameworks I found and field-tested until they held up or fell apart, and lessons that no book could have taught me.
Over time, I started combining the parts that worked and dropping what didn't — adapting things to fit real life, not textbook life. What you see in The Codex isn't any single system. It's the accumulation of all of it, refined into something I use every day.
I kept most of it in notebooks, whiteboards, and sticky notes for years. The Codex is just the decision to finally build it properly — cleaner, shareable, and available to anyone who wants it.
The Bigger Picture
The Operating System for Humans
The Codex is a growing collection of tools, frameworks, and decision models that help you think clearer, move faster, and waste less of your most valuable resource: attention.
Some are productivity tools. Some are decision frameworks. Some are just reframes — one sentence that changes how you see a problem. All of them are things I've actually used. None of them are things I read about once and thought sounded nice.
The Tools
Built from real life. Not theory.
Every tool in The Codex comes from somewhere real. Here's the honest story behind each one.
Tool #1 · Focus
7 Buckets
A mentor taught me this one. We used to have them physically displayed on a wall at the office. Seven buckets, written out, visible to everyone. Once a week, the whole team would sit down and go through each one. What's getting attention? What's being neglected? What needs to shift? Then every person maintained their own set of seven buckets too.
It does one thing well: it forces me to name priorities. Not a to-do list — a map. Career, health, relationships, finances, learning, family, something personal. When you see all seven in front of you, you stop pretending you can do everything at once. You stop taking on more than you can actually finish. I built this first because it's the one I couldn't function without.
Tool #2 · Decisions
Decision Tiebreaker
My father taught me this. He was an engineer, and whenever he hit a technical problem he couldn't crack, he'd structure the problem clearly, then step away and let his subconscious do the work. Sleep on it. Come back. The answer was usually there.
I've been practising this for years — business decisions and life choices I'm glad I didn't rush. The gut-feel check, the sleep-on-it test. These aren't tricks. They're how good decisions actually get made. Most of the time, you're not stuck because the decision is hard. You're stuck because you haven't written it down and looked at it properly. This tool just makes that process faster.
Tool #3 · Strategy
Goal Map
This is inspired by McKinsey's Three Horizons model. The moment I heard it, I knew it was a tool for me — and I've been using it ever since. Most people live almost entirely in Horizon 1, current responsibilities, daily fires — and wonder why they never make progress on what actually matters to them. I use this to audit where my energy is going. If I'm spending 90% in Now and nothing in Future, that's a signal. The Goal Map just makes that invisible thing visible.
Tool #4 · Breathing
Two-Minute Reset
This is one of my favourite breathing exercises. Box breathing uses four equal phases: breathe in, hold, breathe out, hold. It shares an emphasis on breath control with yoga's pranayama practices. Research suggests that slow, structured breathing can support relaxation, but results vary by technique and person. A short session is a chance to pause, not a promise of a specific physiological effect.
If you like this one, there are many more breathwork techniques available. This is just the starting point.
Tool #5 · Accountability
Earn It
I'm a big believer in self-accountability and self-discipline. Not the performative kind — the quiet, daily, nobody-is-watching kind. This is the model I use to keep myself honest.
It came from a frustration with treat culture — the idea that you reward yourself regardless of whether you've done the thing that earns the reward. Earn It is a simple points economy: you earn for the hard stuff (exercise, deep work, early mornings) and spend on the good stuff (a proper meal out, screen time, whatever you'd normally feel guilty about). When you earn it first, you enjoy it more. I've been running a version of this for years. Now you can too.
Tool #6 · Relationships
Love Jar
This is the app I wish I'd had decades ago. I think it would have changed how I showed up in relationships.
I've been following Gottman's research for a while — specifically the work on the Emotional Bank Account. The core finding is that relationships succeed or fail not on the big moments, but on the daily ratio of positive to negative interactions. That idea stuck with me. But knowing it and doing something about it are two different things.
The Love Jar makes it operational. Two people, one shared jar, small gestures tracked over time. Not as surveillance — but as a shared habit. A simple, visual way to see that you're both investing. No complexity, no overthinking. Just a way to pay attention to the thing that matters most and usually gets tracked least.
Tool #7 · Confidence
Win Jar
Years ago, a mentor of mine said four words that have stuck with me ever since: "Success breeds success." The idea is simple but profound. Confidence isn't something you find or wait for — it's built, win by win. Each one you notice makes the next one more likely. Each one you ignore costs you twice: once when it happens, and again when you forget it ever did.
The problem is that the brain's default setting is the opposite. It clings to the one thing that went wrong and forgets the ten that went right. Left alone, you end most weeks feeling like you achieved nothing — even when the evidence says otherwise.
The Win Jar is the antidote. Every time something good happens — small, large, quiet, loud — you log it. Two seconds. The number grows. The streak grows. Sun badges appear as you cross milestones. And on the bad days, you open the jar and scroll. The proof is right there. Wins compound. So does the confidence that comes with them.
The Philosophy
Simple tools. Real results.
Every tool in The Codex is built on one rule: you should be able to understand it in under a minute and start using it in under five. That's the bar. If a tool can't clear it, it doesn't belong here.
The reason is simple. Complicated tools don't get used. They get bookmarked, maybe opened once, then forgotten. The tools that actually change how you operate are the ones so clear and so quick that you run out of excuses not to use them. That's what I'm building toward.
