Here's how to do a brain dump: set a timer for 10 minutes and write down everything on your mind, including tasks, worries and ideas, without sorting. Then sort the list into groups like today, later and not mine. Finally, pick one small next step and do it. That last step turns a messy list into action.
You only need paper and a pen, or a notes app. Below are the steps, prompts to get you going, a worked example, and what research says about why writing things down and planning helps.
A brain dump is a quick, unfiltered list of everything taking up space in your head. It isn't a to-do list yet, and it isn't a journal entry. The point is to get it all out first, so you can deal with it on paper instead of juggling it in your head.
There's a reason this helps. Psychologists E. J. Masicampo and Roy Baumeister found that unfinished goals caused intrusive thoughts during an unrelated reading task. When participants made specific plans for those goals, those effects went away. Their conclusion: committing to a specific plan "may therefore not only facilitate attainment of the goal but may also free cognitive resources for other pursuits."
That's why a good brain dump has three steps, not one. Writing everything down is the start. Making a plan is what lets your mind let go.
Set a timer for 10 minutes.
Write one item per line. Don't sort, judge or fix spelling.
Include small things ("buy batteries") and big ones ("sort out money").
When you stall, use the prompts below.
Stop when the timer ends or your head feels quiet.
Read the list once and give each item one label:
Today: it has to happen today.
This week: it matters soon, but not today.
Later: someday, or when there's time.
Ask: someone else should do it, or you need their help.
Drop: not yours, not needed, or already done.
Worry: nothing to do yet. Write when you'll check on it again.
Western Australia's Centre for Clinical Interventions suggests numbering a to-do list from most important to least important, then breaking each task into all the small steps or "chunks" it involves. Do that for your Today items.
Choose one Today item and write the very next physical action, plus when you'll do it. "Taxes" becomes "Find last year's tax return in the filing box, 4 pm today." Then do it.
Make the plan one you mean to keep. In Masicampo and Baumeister's study, the people who went on to carry out their plans were the ones who had no more intrusive thoughts. If even the next step feels too big, our guide on how to start a task has more ways in.
Read these slowly and write whatever comes up:
What's due this week?
What have I promised someone?
What's bugging me at home?
Which errands keep slipping?
Who do I need to call, text or email?
Which bills, forms or appointments are coming up?
What am I worried about?
What's half finished?
What do I keep meaning to look up?
What would make tomorrow easier?
Which ideas don't have a home yet?
What could I stop doing?
Here's a short dump, exactly as it might come out: dentist?, email Sam about invoice, laundry, Mom's birthday Saturday, weird noise in the car, renew passport, fix bike tire, budget, reply to group chat.
After sorting, it looks like this:
Today: email Sam about the invoice; laundry.
This week: Mom's birthday gift by Saturday; call the dentist.
Later: check the passport expiry date; fix the bike tire; set up a budget.
Worry: the car noise. Next step: book a mechanic, so it moves to This week.
Drop: the group chat doesn't need a reply.
The one next step: open email and send Sam the invoice. Now.
Paper is fast and free of notifications, and crossing things off feels good. It's easy to lose, though.
A phone is always with you, it's searchable, and dictation helps when typing is slow. The risk is getting pulled into other apps.
Use whichever you'll actually reach for. A good mix is to dump on paper, then move only the Today and This week items into your calendar or reminders.
Daily, 5 minutes: first thing in the morning or at the end of the workday.
Weekly, 15 to 20 minutes: a bigger sweep to clear old items and review the Later list.
Whenever you feel overloaded: it's a reset you can do anywhere.
Before bed: a short list of tomorrow's tasks.
That last one has some research behind it. In a 2018 sleep lab study of 57 healthy young adults, people who spent 5 minutes writing a to-do list for the next few days fell asleep significantly faster than people who wrote about tasks they had already completed. The more specific their to-do lists, the faster they fell asleep. It was one small study, but it's an easy thing to try.
Not quite. Journaling often explores feelings and events. A brain dump is a fast list aimed at action: get it out, sort it, then pick a next step.
About 10 minutes for the dump and 5 for sorting and choosing a next step. A weekly version can run a little longer.
Put dated tasks in your calendar or reminders, keep the Later list where you'll see it at your weekly review, and cross out the rest. Then do the one next step you chose.
It's worth a try. In one small study, writing a specific to-do list for 5 minutes at bedtime helped people fall asleep faster than writing about what they'd already done.
If you'd rather dump straight into your phone, the Now app has a Brain Dump box that takes typed or dictated text and splits it into tasks. A daily plan holds up to three tasks, with a "parking lot" for everything else, and the home screen shows one task with a suggested first step you can edit, swap or shrink. It doesn't diagnose, treat or manage ADHD or any medical condition, and your tasks are stored on your iPhone with no account.
