The ADHD brain dump: get it out of your head without building a system

There's a particular kind of tired that comes from carrying forty half-remembered things around in your head. The dentist. The email you owe. The thing your friend asked you to send. The bill. All of it circling, none of it written down, each one popping up at the worst possible moment.

A brain dump is the fix, and it's the simplest one there is. Write everything down. All of it. Then stop.

The trick is that second part.

Why the head is a bad place to keep tasks

Working memory, the bit of your mind that holds things "in the air" while you're doing something else, is one of the areas ADHD affects most. CHADD lists working memory among the executive function skills that people with ADHD commonly struggle with. In practice that means things fall out of your head with no warning, and the only way to stop them falling out is to keep re-thinking them. Which is exhausting, and which is why you can feel busy all day having done nothing.

Writing a thing down does two jobs. It saves the thing somewhere reliable. And it gives your brain permission to stop rehearsing it.

How to do the dump

Keep it low-tech and fast. The goal is to empty, not to organise.

1. Pick one place. A sheet of paper, a notes app, your to-do list. Anywhere, as long as it's one place.
2. Set a timer for ten minutes. Not because you'll need all ten. Because a timer makes it a bounded task instead of an open-ended one.
3. Write everything. Work, home, people, worries, the thing you've been avoiding for three months, "buy stamps". Don't judge, don't group, don't skip things because they're too small or too big.
4. When you slow down, prompt yourself. Go through areas: work, home, money, health, family, friends, the car, the house, things you've promised. Each one usually shakes out another two or three.
5. Stop when the timer goes. You'll remember more later. Add them then.

That's it. You now have a long, messy list. It's supposed to look like that.

The trap: organising it "properly"

This is where most brain dumps die. You look at the pile and think: now I'll sort it. Categories. Priorities. A new app with projects and tags. An hour later you have a beautiful structure, you're exhausted, and you haven't done anything on the list.

Worse, you've now built something that needs maintaining. Next week the structure is out of date, and looking at an out-of-date system feels worse than looking at a plain pile.

The dump is the valuable part. The sorting is mostly procrastination in a nice outfit.

Do the minimum sorting that changes what you do next

There is a small amount of sorting worth doing. The test is simple: does this change what I do in the next day or two? If not, skip it.

• Cross out anything that isn't yours. Things you've decided not to do, things that are really someone else's, things that were a worry rather than a task. Be generous with the pen.
• Rewrite the vague ones as actions. "Mum" becomes "call Mum about Sunday". "Car" becomes "book MOT". If you can't think of the action, leave it as is. It'll become clear when it becomes urgent.
• Pick one thing to do next. Just one. Mark it somehow.

Optionally, give things a rough colour by area of life so the list is scannable. Two seconds per item, no thought required, and you can skip it.

Everything else, leave alone. No priority levels, no due dates, no folders.

Turn it into your actual list

If you did the dump on paper, move it into wherever you'll actually look. This is a good moment to be honest: if the place you look is your phone, put it on your phone. If you dumped into a notes app, it's already there.

The important thing is that the brain dump becomes the list, not a separate document that sits next to the "real" list. Two lists means twice the places to check and half the trust in either.

Keep dumping, in small doses

The big brain dump is a reset. The habit that keeps it working is much smaller: whenever something pops into your head, write it on the list immediately, in the middle of whatever you're doing. Don't evaluate it. Don't decide where it goes. Just capture it and return to what you were doing.

This is easier with a list that's always one tap away and doesn't ask you questions when you add something. The moment adding a task requires choosing a project, you'll start "remembering it for later" instead.

What to expect

Immediately after a brain dump, most people feel lighter and then slightly alarmed at the length of the list. Both are normal. The length was always there. It was just in your head where you couldn't see it. On paper it's finite, which is better.

Over the following days you'll find things surfacing that you forgot to write down. Add them. And you'll find things on the list that, now you can see them, you decide not to do. Cross them off. That's the list doing its job.

A note on OneList

We built OneList to be a good place to dump into. Adding a task is one line and Enter, with no project or date to choose. There's one list for everything, tasks can be coloured with one of five colours if you want them to be, and you star the single thing you're doing next to move it into the Now section at the top. Nothing else to set up.

It's free, works in your phone browser and you can try it without an account. If you've got a head full of things right now, set a ten-minute timer and empty it.
