Organising with ADHD: why classic systems fail

“This time it will be different.” The planner is new, with thick covers and coloured tabs. The first week is perfect: every day has its own list, every task its own colour, and on Sunday there is a weekly review. In the second week some days are empty. In the third week the planner is lying under a pile of post. In February you find it, leaf through those lovely first pages and feel a familiar feeling: you didn’t manage it again.

If you recognise yourself in this, you are not alone. Many adults with ADHD (attention deficit hyperactivity disorder) have a drawer at home, or a folder on their phone, full of organisation systems they have tried and abandoned: to-do apps, calendars, spreadsheets, methods with foreign names. Each one began with hope and ended in shame.

In this post I want to explain why this happens — and why the reason is not a lack of willpower. I will not offer yet another system that is bound to work this time. Instead, I will show the assumptions classic systems rest on and why, with ADHD, things get stuck precisely there.

First, though, a clarification: ADHD is diagnosed by a psychiatrist or a clinical psychologist. If you find organisation hard, there can be many reasons for it, and ADHD is only one of them.

Systems built for different heads

A meta-analysis published in 2009 by Viktória Simon and colleagues estimated that around 2.5 per cent of adults have ADHD. That means most of the people who invent, sell and recommend organisation systems do not have ADHD. And their systems are built for heads like their own.

Almost every classic system carries a hidden assumption: that you will remember to use it. A to-do list only works if you look at it. A calendar only works if you enter the meeting and open it again later. A weekly review only works if you remember it on Sunday and find the will for it. The system is supposed to be a memory aid — yet using it requires the very memory it is meant to replace.

For most people this assumption is solid enough. With ADHD, however, these exact abilities — working memory, planning, getting started and keeping going — are the ones that fluctuate. Professionally we call them executive functions. A system that needs reliable executive functions in order to help with executive functions will, with ADHD, break sooner or later.

ADHD is a problem of doing, not of knowing

The psychologist Russell Barkley, one of the most influential ADHD researchers, developed a model in which the core of ADHD is a difficulty with self-regulation — with the capacity to stop, hold a goal in mind and act on it, even when you cannot see or feel it. From this he drew an idea he often repeats: ADHD is not a disorder of what you know, but of doing what you know.

This matters, because almost all organisation advice hands out knowledge. How to break tasks down. How to set priorities. How to plan your week. Most people with ADHD already know all this, often better than others, because they have read every book. What they lack is not knowing what they should do. What they lack is the bridge between knowing and doing at the right moment.

That is why Barkley talks about the point of performance: help has to be there, and then, where the action happens. Not in a planner in a drawer, but on the door as you leave. Not in an app you have to open, but in a sound that goes off by itself. Not in a Sunday plan, but in the moment you have to decide what you will do now.

Important is not the same as interesting

The second hidden assumption of classic systems is that a task’s importance will get you going. Once you know something matters, you will do it. With ADHD, though, attention is often tied to interest, novelty, challenge or immediate pressure — not to importance.

In 2009, Nora Volkow and colleagues used brain imaging in adults with ADHD to describe differences in the reward system driven by dopamine. These differences were linked to symptoms of inattention. The researchers suggested they could explain why, with ADHD, it is so hard to persist with tasks that bring no quick reward. It is one explanation, not the whole story, but it fits well with what people with ADHD describe: a tax return that is urgent but dull can wait until the last day, when panic finally gets it going.

This means that systems built on “just start, because it’s important” miss the engine. Systems work better when they bring something into the task that actually draws attention: another person, a time limit, a small reward, a game or novelty.

What you can’t see doesn’t exist

Many people with ADHD describe how things they cannot see simply vanish from awareness. A bill in a drawer does not exist until the reminder arrives. A meeting in an app does not exist until the alarm rings. The vegetables in the bottom drawer of the fridge do not exist until they start to smell.

This is linked to working memory — the capacity to hold something in mind when it is not in front of you. If working memory is less reliable, the environment has to do the reminding. That is why, with ADHD, open shelves are often more useful than closed cupboards, clear boxes more useful than opaque ones, one board on the wall more useful than five apps on the phone.

People without ADHD sometimes see this as mess. “Why do you have everything on the desk?” The answer is often: because that is the only place where it exists. Putting things away in drawers can be order for one person and a way of losing them for another.

Time you can’t feel

The third assumption is that time flows evenly and that you feel it. That you will know how long is left until a deadline and adjust accordingly. With ADHD, though, time often exists in only two forms: “now” and “not now”. A deadline in three weeks sits in the “not now” category together with a deadline in three months — until it suddenly becomes “now”.

I have written about this in more detail in Time blindness: why the clock works differently with ADHD. For organisation, what matters most is this: time has to become visible. An analogue clock instead of a digital one, an hourglass or a timer that shows how much time is left, a wall calendar where days are physically crossed off. Anything that turns time from an abstract idea into something you can see.

It is also worth adding a margin to every estimate of “this will take half an hour”. Not because you are lazy, but because estimating duration is often unreliable with ADHD — and it is usually wrong in the same direction.

When the novelty fades

Let us go back to the planner from the start. Why did the first week work? Because it was new. Novelty is a powerful engine for attention with ADHD. When it fades, the system it was driving fades too.

That is not proof that the system was the wrong one, and it is not proof that you are incapable. It is simply a trait you can plan around. Some people with ADHD therefore change systems deliberately: a few months on paper, then an app, then a board. Instead of experiencing each change as a defeat, they see it as part of the system. Organisation is not a single decision for life, but something that changes along with you.

It is similar with routine. For people with ADHD, routine is often both the most useful and the hardest thing to sustain. It helps to keep it as short as possible, attached to something that happens anyway (coffee, brushing your teeth, coming home), and not built on the assumption that you will never break it.

A conversation about the new planner

When it comes to organisation, the people close to us often have something to say too. Something like this (composed, not a real person):

“Have you bought another planner?”
“Yes. This time it’ll be different.”
“You said the same last year.”
“I know. And when you say that, I feel like I’m ten years old.”
“I didn’t mean it like that. Just … what if the problem isn’t the planner?”
“What if the problem isn’t me?”

Both of those last sentences are true. The problem is not the planner, because no planner can replace executive functions. And the problem is not “in her” in the sense of a character flaw, but in the fact that the system was not built for her head. When the conversation moves from “why can’t you manage” to “what would actually help you”, room opens up for solutions.

The shame that builds up with every abandoned system

Every abandoned planner leaves a trace. Not only blank pages, but also a quiet sentence: “You failed again.” Once enough of these sentences pile up, organisation becomes an area you avoid because it is too painful. And avoidance makes the chaos even bigger.

Shame: the emotion that whispers “There is something wrong with me” often takes root, with ADHD, in precisely these everyday things — missed deadlines, unanswered messages, an untidy flat. For some people it turns into perfectionism: if I can’t do it perfectly, I won’t start. I have written about how perfectionism and procrastination feed each other in Perfectionism and overthinking: two sides of the same fear, and you will also find a short explanation in the knowledge base under procrastination.

That is why one of the most practical organisational skills is surprisingly emotional: being able to return to a system without punishing yourself. A planner that has been lying under the post for three weeks is not proof of failure. It is a planner you can open again today on today’s page — without catching up on everything you missed. Kristin Neff’s research on self-compassion suggests that a kinder attitude towards yourself after mistakes does not lead to laziness, but more often to another attempt. There is more on this in Self-compassion instead of self-criticism.

What research shows about help

Organisational difficulties with ADHD are not just a matter of home hacks. The European consensus statement on adult ADHD, published in 2019 by Sandra Kooij and colleagues, recommends a comprehensive approach: alongside any medication, psychoeducation, adjustments to the environment and psychological approaches. Medication is decided by a doctor — a psychiatrist who knows your history and health.

Among psychological approaches, the most researched is cognitive behavioural therapy adapted for adults with ADHD. In 2010, Steven Safren and colleagues published a study in which adults who were already taking medication but still had symptoms benefited more from this kind of therapy than from a comparison programme of relaxation and education. Mary Solanto developed a group programme focused specifically on time management, organisation and planning. What both have in common is that they do not only teach “what to do”, but practise how to do it in real life — at the point of performance.

There is also something that is in no protocol: relationships. Organisation with ADHD rarely happens in a vacuum. It happens in a partnership where one partner starts carrying the mental load for both, in a family where a child may have ADHD too — that is the subject of When a parent and a child both have ADHD — or at work. On the latter, when it comes to running your own business, I have written in ADHD and entrepreneurship: a gift and a burden at once.

Exercise: reviewing one sticking point

Instead of trying to sort out your whole life at once, choose one single thing that keeps slipping away from you. The exercise takes fifteen minutes.

1. Choose one sticking point. Not “organisation in general”, but something concrete: bills, keys, answering emails, laundry. Just one.
2. Write down exactly where it gets stuck. At memory (I forget it exists), at starting (I know, but I don’t begin), at persisting (I start, but don’t finish) or at time (I think I still have time)?
3. Ask yourself where the action happens. Where are you physically standing when you should be doing it? Move the reminder, the object or the tool there — not into a planner.
4. Shrink the first step until it is ridiculously small. Not “pay the bills”, but “open the envelope”. Not “tidy the kitchen”, but “put three things in the dishwasher”.
5. A week later, check without judgement. Did it work? If not, your character is not to blame — change one element and try again.

At the end of the week you may have solved just one sticking point. That seems like very little. But one sticking point solved in a way that works for your head is worth more than ten systems that would work for someone else.

Where this explanation falls short

Not all disorganisation is ADHD. Difficulties with organisation also appear with depression, burnout, anxiety, lack of sleep, after giving birth, during major life changes, or simply when you have too many tasks for one pair of hands. If the difficulties appeared only recently and were not there before, the reason probably lies elsewhere. For an assessment, see your doctor.

Hacks are not treatment. Adjusting your environment can help a great deal, but it does not replace a professional assessment and, where appropriate, treatment. If organisational difficulties seriously threaten your job, relationships or finances, you deserve more than advice from the internet.

Not everything is on you. Some environments are simply overloaded. If nobody in your workplace can keep track of all the deadlines, the problem is not only your executive functions. And if you carry the organisation at home for everyone on your own, it is not only about ADHD, but about how the work is shared.

There is no one right system. What I describe in this post are principles, not a recipe. What works for someone else with ADHD may not work for you — and vice versa.

What to remember

• Classic systems assume you will remember to use them — which is often exactly what is hardest with ADHD.
• ADHD is more often a problem of doing than of knowing: help has to be there, and then, where the action happens.
• With ADHD, attention is often driven by interest, novelty or a deadline, not importance. A system can use this instead of fighting it.
• Make time and things visible; see changing systems as part of the plan, not as defeat.
• The most important skill may be an emotional one: returning without punishment. Leave diagnosis and treatment to a psychiatrist or clinical psychologist.
