Being a healthy human in your community, managing the house, owning a vehicle, technology, travel. Everyone has life admin, usually spread across cloud drives, download folders, and ten years of email.

You could build a Johnny.Decimal system for all of it yourself. It took me and Lucy a month: we trawled hard drives, email, papers, memories. Decades of history. We used that to build the Life Admin System.

An ID for everything

150+ IDs across 5 categories give you a place for everything. You get a searchable index with 10,000 words of description and examples. A folder structure and text files to build your index. And dedicated community support channels.

Download it and move in. You'll be more organised by the end of the day. It has saved me hundreds of hours in the 2+ years I've been using it.

“The life admin pack has helped me more than any other productivity book or course I have purchased in the past. It's well thought out and does the thinking for you so you don't have to – covering all of your life admin from health and education to travel and money.”

— Jade

Having neat files is nice. But knowing what to do next, and having a system that leaves you in control of your life – that's the Johnny.Decimal superpower. These courses show you how to get there.

The Life Admin System doesn't contain areas for your hobbies, side hustle, or that tennis club you manage – that's stuff unique to you, so you need to design it yourself. Use the Workshop to do that.

The Workshop

In our 5-hour Workshop, my partner Lucy takes apart her own life and rebuilds it as a Johnny.Decimal system. You build yours alongside her – by the end, you have a working system of your own. (We created the Life Admin System using exactly this process.)

“Watching Lucy build her system with Johnny's guidance gave me the confidence to build my own system. One week in, I'm already feeling more organized and productive.”

— Cole

Task and Project Management

Tasks keep you on top of your life. Projects drive it forward. Over another 5 hours, I show you how I run both in my own system, every day. The aim: a 'comfortable awareness' of everything you need to do. I've never felt more organised, or more in control.

“All 3 of my email inboxes are down to zero, all of my expenses are coded, my projects are not lost and forgotten and I, for the first time in my adult life, feel like I'm starting the year better off than I finished last year.

I think this is because your Task and Project Management philosophy fully unlocked the benefits of the Johnny Decimal system. The ease and clarity with which I've been able to manage the details of my life, both personal and professional, would have been unimaginable at this time last year.”

— Jeff, Lovett Sundries

Mini-courses

The rest are mini-courses: some are JDU-only, others are things we've taught on YouTube. We've collected those here, put them in the right order, and removed the ads.

• Johnny.Decimal 101: the system's documentation, explained by me on video.
• Working with Johnny.Decimal: how I use my system to run my own business.
• Online security essentials: how to be safer online.
• Learn with Lucy – Excel: a bonus 14-hour (!) course. I taught Lucy – a total beginner – how to use Excel.

You get all of it with Pro, plus everything we add in the future.

Tools to help you manage your system. Today that's an MCP server and API access to the site contents. Ask your LLM questions about your system, or write your own tools.

More coming later in 2026. Your Pro membership will include everything.

You started a business because there's a thing that you do better than anyone else. But you find yourself dealing with the boring admin that we all share: registrations, filing, receipts, returns. Tracking it all is a nightmare.

As small business owners ourselves, we know this frustration. We solved it so that you don't have to.

Me and Lucy spent five months analysing our combined 50+ years of experience as freelancers, contractors, consultants, and small business owners.

We considered all shapes of business in this design: farmers, gardeners, drivers, retail, software engineers, consultants. Whatever you do, you'll fit in.

200+ IDs across 20+ categories in 5 areas give your business a place for everything. You get a searchable index with 50,000 words of description and examples.

This system runs our business.

Regular Zoom sessions

We hold open Zoom sessions every fortnight in alternating timezones. Bring your questions. And if you need it, you can book a 1:1 with me.

The Life Admin System and all courses and tools are included.

“We switched our whole business over and now everyone's on the same track. Everything has a logical, decimally defined place – and it's easy for someone else to find that document again when they need it.”

— Des, Datum Machines

“I took all the productivity courses there are. Each was super expensive and my life got maybe 10% less of a mess. Then I took the [Workshop], spent 2 weeks to integrate the system – 1.5 years later, my life is still organized and I'm finally in peace.”

— Taras

“I come from PARA and liked the system at first. But since there is no index it went all over the place. Cluttered stuff everywhere and no structure. Folders in folders in folders. It. Was. Pain.

Your Johnny decimal system gives me structure. A clear plan where something lives and what to expect there. No artificial nice names or acronyms. It resonates a lot with me and how my brain works.”

— @salutalice

“I'm a big fan of what Johnny has developed here. Excellent production values. Great value for money. If I was still consulting to business clients, this program would be on my list of recommendations every time.”

— Andrew, on LinkedIn

“I've tried all of the other popular organizational frameworks, and this is the first time I feel like I trust my system more as it grows.”

— Victoria

What software do I need?

The system works with whatever you already use. You'll need an app to manage your JDex – I recommend Obsidian but you can use any app that either lets you keep a list of notes, or is a database.

People use and enjoy Bear, NotePlan, DEVONThink, Notion, Craft, Emacs, and more. You can use Apple Notes but its import feature isn't very good. Please don't use OneNote, it's … just no.

Where is my data stored?

Wherever it is today: I never touch your data. What I give you is structure and process. If your data is on your iCloud Drive today, that's where it stays.

What happens after I buy?

If you're not signed in, you'll receive an email after your payment is processed. It comes from hello@johnnydecimal.com and has a link to create your account. Click that, set a password, and you're in.

If you're already signed in, you'll get instant access to your purchase. You can create a free account on the homepage if you need one.

What if I need support or have more questions?

Email me. I answer every message personally, usually within 24 hours.

What if I don't like it?

Forward your purchase receipt to hello@johnnydecimal.com. If you want to tell us what we could have done better, please do: it really helps. But no pressure. You can just say 'I'd like a refund'.

If you can't find your receipt, tell me what you purchased and when and I'll look it up. (You should be more organised. Ha ha.)

We know you're all tired of subscriptions, so we've made this a membership that you only have to pay for once. We work tirelessly to add valuable stuff to it – so tell us what you need. We build what our community asks for.
