Brain Dump

Empty your working memory onto paper so it can stop holding everything at once.

What it is

A brain dump is the act of writing down everything currently rattling around in your head, fast, without organising or judging. You then look at the pile and decide what's actually a thing.

ADHD working memory is unreliable in a very specific way: it doesn't lose information, it holds too much at once and then drops everything in a panic. The brain dump moves that holding job onto paper, which never panics.

When to use it

  • You can't sleep because your brain keeps rehearsing tomorrow
  • You feel busy but can't say what you're busy with
  • You're switching between five tasks and finishing none
  • Sunday night, before a week that already feels like too much
  • The moment you notice a tab-overload sensation behind your eyes

How to do it

  1. Paper, not screens. A blank A4 sheet is best. Screens invite organising and tagging. The whole point is to not organise yet.
  2. Set a timer for ten minutes. Brain dumps without a timer expand to fill the day.
  3. Write everything. Tasks, worries, half-thoughts, song lyrics, that thing your aunt said. No order, no categories.
  4. Don't edit while writing. You're emptying, not curating.
  5. When the timer ends, look at the page and circle the three things that are actually next actions. Everything else can wait. Most of it can wait forever.

An example

I lay in bed for forty minutes one Tuesday, unable to sleep, brain looping through a tax form, a friend's text, a bug at work, and a vague sense I had forgotten something.

I got up, grabbed paper, wrote for nine minutes. The page had 31 items. Three of them mattered:

  • Reply to Sam (2 min)
  • Find out the tax form deadline (probably fine, just need to check)
  • Email Pedro about the bug

I went back to bed at 11:30pm. Asleep by 11:35pm. The brain hadn't been holding 31 things; it had been holding "an undefined number of things" which is much worse.

When this fails

  • You organise as you write. The whole point is the absence of structure. Bullet points are fine; categories are not.
  • You do it digitally and then keep tweaking it. Phones lie to you about which note-taking app is the right one. Paper is faster than Notion every time for this.
  • You never review the pile. A brain dump that doesn't end with "OK what are the three real things?" is just a list. The triage step is where the relief comes from.

Try it this week

Tonight, before bed, set a ten-minute timer. Write everything in your head onto a single page. Circle three real next actions. Put the page somewhere you'll see it in the morning.

Notice whether you sleep differently.
