Brain dump: how to empty your head and sort it into tasks
A brain dump is writing down everything on your mind, all at once and in no order, so you can stop carrying it in your head. This guide covers why it helps, six steps that end in a sorted list, an example, and what to do when the dump doesn't help.
Why a full head gets nothing done
Your head is a poor place to keep a list. In a review of the memory research, Nelson Cowan (2001) put the number of separate things people can hold in mind at once at about four. A normal week asks you to remember far more than that: the email to answer, the form due Friday, the idea for the shop, the call you said you'd make.
So the open items take turns. Each one comes back at a bad moment, usually while you're doing something else, and pulls you off it. Research on unfinished goals by Masicampo and Baumeister (2011) found that a goal left open kept intruding on people's thoughts and hurt their work on an unrelated task. Making a specific plan for it eased that pull, even before any of the work was done.
A brain dump is the first half of that plan. Once everything is on one page, you can see it, compare it and choose. The second half, the sort, turns the page into a short list of next steps. Skip the sort and you've only moved the mess from your head to paper.
Six steps to a brain dump that ends in a plan
Give it 20 to 30 minutes the first time: about 10 to write, the rest to sort. After that, a weekly dump takes 15.
-
Set a timer for 10 minutes
A limit keeps the dump moving and gives you a clear end. Use paper, a notes page or your voice. Anything that lets you get words out quickly works.
-
Write down everything, one item per line
Tasks, errands, ideas, worries, half-thoughts, things you said you'd do. Don't sort, judge or fix the wording yet. "Car thing" is fine. If the same item comes up twice, write it twice.
-
Sweep the corners
When you run dry, go area by area: work, home, people you owe a reply, money admin, appointments, the side business, things you're waiting on from others. Each prompt usually shakes loose two or three more lines.
-
Sort every line into one of four piles
A task is something you can do. An idea is something you might do one day. A worry is something on your mind with no action yet. The rest you can cross out. Mark each line T, I, W or a line through it.
-
Turn each task into a next step
Start it with a verb and make it small enough to finish in one sitting: "Car thing" becomes "Call the garage to book the service". If a task is really a goal, such as "Get the shop going properly", write its first step as the task. Give a date to anything with a deadline.
-
Pick one to three tasks for today
Everything else gets a date or waits on a someday list. For each worry, ask whether there's a step you can take. If there is, it becomes a task. If not, it stays on the page, written down and out of your head.
One brain dump, sorted
A Sunday evening dump from someone who runs an online shop on the side came to 16 lines: nine tasks, three ideas, two worries and two to cross out. One task turned out to be a goal, so it got steps of its own.
Example goal
- Long-termMake my online shop my full-time income
- Mid-termReach 30 orders a month
- Short-termList 10 new products with photos
Today's taskPhotograph 3 products
We wrote this example ourselves. The dump line was "Get the shop going properly". It was too big to be a task, so it became a goal with a first step small enough for one evening.
The rest of the list sorted quickly. "Reply to the supplier about the late box" and "Renew the business licence by the 15th" became tasks with dates. "Try a holiday gift bundle" went on the someday list as an idea. "Worried sales are slow" had a step in it, so it became "Check last month's orders by product". The other worry, about the weather on market day, had no step, so it stayed on the page.
In LeapSteps you can do the dump out loud. Tap the mic in the quick-add bar, talk, then tap Stop; recordings over two minutes are thrown away. You'll see what was heard and the tasks drafted from it, with any dates you said already set, and you pick which ones to add. A task you add with no date goes into Today, and anything that can wait can be dragged onto the Someday header. A task can also link to a goal's next step, as in the screenshot above.
Your first week
Seven short tasks to make the brain dump a habit. The aim this week is one full dump and one sort, then a short daily top-up, not a perfect list.
- Do a full brain dump with a 10-minute timer10 min Everything on one page, in no order.
- Sweep the corners: work, home, people, money admin, waiting on5 min The prompts find what the first pass missed.
- Mark every line as task, idea, worry or cross-out10 min The sort is where the dump turns into a plan.
- Rewrite each task as a next step that starts with a verb10 min A clear first step is easier to start than a vague one.
- Add the tasks to your list, with dates where they're due10 min One trusted list, so the page can go in the bin.
- Each morning, dump anything new and pick one to three tasks for today5 min A small daily top-up stops the pile building up again.
- At the week's end, check which tasks moved and redo the dump15 min Items that didn't move are usually too big or too vague.
An ADHD brain dump
The method doesn't change with ADHD, but a few things make it easier to finish. Keep the timer short, five or ten minutes, and stop when it rings even if more is coming. Say it instead of writing it if the blank page is the hard part. Do the sort later, on a different day if you need to; a dump you sorted is worth more than a long one.
Then keep today's list very short, one to three tasks, and put just one of them in front of you with a timer. Our page on planning with an ADHD brain covers more ways to make starting easier. This guide is about getting tasks out of your head and onto a list; it isn't medical advice.
What the research says about open loops

You can hold about four things at once
A review of the memory research put the number of separate items people can keep in mind at about four. That's why the dump goes on a page or into the app, where nothing has to wait its turn in your head.

A plan quiets an unfinished goal
Unfinished goals kept intruding on people's thoughts and hurt their work on other tasks, until they made a specific plan for them. That's why each task gets a next step, and a big one can link to a goal's next step.

Decide when, where and how
Across 94 tests, plans that spelled out when, where and how people would act had a medium-to-large effect on reaching their goals. That's why tasks from the dump get a date, and a due time can bring a reminder.

These studies test the ideas behind LeapSteps, not the app itself. Most of them studied students in a lab or a classroom. Checked October 30, 2026.
When the brain dump doesn't help
Sometimes the page fills up and nothing changes. These are the usual reasons, and the next move for each.
-
You wrote it all down and never sorted it.
Then the page is just a second head. Book ten minutes for the sort, and do it before you add anything new. Masicampo and Baumeister found it was the plan, not the writing alone, that eased the pull of an open goal.
-
The list is longer than the week.
It usually is. Pick one to three tasks for today, date the ones with deadlines, and move the rest to someday on purpose. A short list you finish beats a long one you avoid.
-
The same items come back every week.
They're too big or too vague to start. Cut each one to a first step you can finish in one sitting. Our guide on how to stop procrastinating covers the task you keep avoiding.
-
Everything feels urgent.
Pick the one task that matters most and do it first, before the easy ones. Eat the frog shows how to choose it, and a plan for when you'll start helps it happen.

Questions, answered
What is a brain dump?
A brain dump is writing down everything on your mind in one go, with no order and no editing: tasks, errands, ideas, worries and half-finished thoughts. The point is to get it all out of your head and onto one page, where you can see it. A useful brain dump has a second step, the sort. You go through each line and decide whether it's a task, an idea for later, a worry or something to cross out, then turn the tasks into small next steps and pick a few for today.
How long should a brain dump take?
About 10 minutes to write and 10 to 20 to sort the first time. A timer helps: it keeps you writing instead of polishing, and gives the dump a clear end. Once you've done one full dump, a weekly one usually takes about 15 minutes in all, because most of your list is already sorted. On busy days, a two-minute top-up in the morning catches anything new before you choose what to work on.
What do I do with worries on the list?
Ask whether there's a step you can take. "Worried sales are slow" has one: check last month's orders. "Worried the car will fail its test" has one too: book the test early. Write those steps as tasks. If a worry has no step you can take, leave it on the page and move on. This guide is about turning what's on your mind into a plan; it isn't a method for managing anxiety, and if worries are getting in the way of daily life, a doctor is the right person to ask.
How often should I do a brain dump?
Most people do best with one full dump a week and a short top-up each morning. The weekly dump catches everything that piled up; the daily top-up catches what's new and helps you pick today's tasks. Some people also do a dump before a big change, such as a new job or a busy season at work, or at the end of a long day so they can stop thinking about work. Do it whenever your head feels crowded and you can't decide where to start.
Can an app help with a brain dump?
It can make the sort quicker, but the thinking is still yours. LeapSteps is our app. Tap the mic in the quick-add bar, say everything, then tap Stop; recordings over two minutes are thrown away. You'll see what was heard and the tasks drafted from it, with any dates you said already set, and you pick which ones to add. Tasks without a date go into Today, and anything that can wait can be dragged onto Someday. If you'd rather not add an app, paper and a pen work on the same idea.
