Brain dump: what it is and how to do one in 10 minutes

A brain dump is exactly what it sounds like: you take everything that's rattling around in your head (tasks, worries, ideas, dates, half-remembered errands) and get it out onto paper or a screen, without organizing it first.

It sounds too simple to help. But holding things in your head takes effort, and a lot of that effort goes into not forgetting. Once it's written down, your brain can stop rehearsing it.

Why a brain dump helps

• It turns a feeling into a list. “I have so much to do” is a feeling. Twelve lines on a page is a list, and a list has an end.
• It separates collecting from deciding. When you try to plan and remember at the same time, you do both badly. A dump is only collecting.
• It shows you what's actually there. Often the list is shorter than the dread suggested, and some items turn out to be worries, not tasks.
• It's friendly to scattered attention. There's no structure to follow, so there's no way to do it wrong. Many people with ADHD find it one of the few planning habits that sticks.

How to do a brain dump, step by step

1. 1

   Set a timer for 10 minutes.

   A time limit makes it a finite job. You're not organizing your life, you're emptying your head for ten minutes.

2. 2

   Write everything, one item per line.

   Tasks, worries, ideas, appointments, things to buy, that thing you said in a meeting. No order, no judging, no fixing spelling.

3. 3

   When you run dry, use prompts.

   Work, home, money, health, people, errands, things you're waiting on. Run through them and see what else falls out.

4. 4

   Stop when the timer ends.

   Even if there's more. You can always add later, and the list doesn't need to be complete to help.

5. 5

   Sort every line into tasks, events or notes.

   This is where the dump becomes useful. See the sorting rules below.

6. 6

   Pick one task and find its first step.

   Not the most important one; the one that would feel best to have done. Then break it down so the first step takes under two minutes.

How to sort a brain dump: tasks, events and notes

A raw dump is a relief, but it isn't a plan yet. Sorting turns it into one. Go line by line and ask one question: what kind of thing is this?

A few lines will be none of these: things you can't control, or tasks that turned out to be someone else's. Cross them out. That's a valid way to finish a line.

A real example

Here's a ten-line dump, exactly as it came out:

dentist?? haven't been in forever
reply to Sam about the deck
mom's birthday is the 14th
we're out of coffee
idea: podcast about old maps
car registration expires soon I think
team sync thursday 10am
the kitchen is a disaster
why did I say that in the meeting
cancel the gym trial before friday

And sorted:

Six tasks, two dates, two notes. Ten minutes ago it was “everything”. Next, pick one task, say cleaning the kitchen, and break it down until the first step takes under two minutes.

How often should you brain dump?

There's no rule. Common rhythms: a short dump every morning before opening email, a longer one at the end of the week, or whenever your head feels loud. The habit that matters more is capturing as you go: when a thought shows up in line at the store, put it somewhere right away instead of trying to hold it until later.

Paper or phone?

Paper is great for a sit-down dump: no notifications, and crossing things out feels good. A phone wins for capture during the day, because it's always with you. Many people do both. If you want paper, there's a free, printable brain dump template with the prompts and sorting boxes built in.
