How to Do a Brain Dump (ADHD-Friendly Steps + Free Template)

By Robin Hale · October 28, 2026

Short answer: Set a timer for five minutes and write everything on your mind on one page, in any order. Then mark each item N (now), L (later), S (someday) or X (let it go), and turn one N item into a tiny first step. That's a complete brain dump.

A brain dump is exactly what it sounds like: getting everything out of your head and onto paper (or a screen) so you can see it. For many people with ADHD, it's the fastest way to go from "I have too much to do and can't start anything" to "OK, I know what's next".

Why a brain dump helps

When tasks, worries and ideas all live in your head, they compete for attention. Writing them down doesn't make them go away, but it moves them somewhere you can look at them, compare them and decide. It also stops the loop of trying to remember everything at once.

How to do a brain dump in 4 steps

1. Dump (5 minutes)

Set a timer. Write anything that comes up: tasks, appointments, worries, half-ideas, "buy batteries", "email Sam", "what was that show?". No order, no categories, no judging. Messy is fine.

Stuck? Try prompts: What's due soon? What am I avoiding? What's bugging me at home? Who do I need to reply to? What do I keep forgetting?

2. Sort with four letters

Go through the list once and put a letter next to each item:

N, now: needs doing today or very soon
L, later: matters, but not this week
S, someday: nice ideas with no deadline
X, let it go: you're allowed to drop it

The X is important. A brain dump is also permission to stop carrying things you're never going to do.

3. Pick one N

Don't plan all of them. Pick one item marked N, usually the one with the closest deadline or the one that will make you feel lighter.

4. Make the first step tiny

Break that item down until the first step feels almost too small: not "do taxes" but "find last year's tax email". If a step makes you hesitate, it's still too big. Write down how long you think it will take, and later how long it really took. Over time that "guess vs actual" note quietly improves your time estimates.

Where the rest goes

N items: onto today's page or this week's priorities
L items: onto a weekly page or a "later" list
S items: onto a someday / parking lot page
X items: crossed out, gone

How often should you brain dump?

Whenever your head feels full. Some people do a quick one every morning, some once a week as part of a weekly reset, and some only when they feel stuck. A useful habit: do one every time you come back after a break from planning, before you plan anything else.

Brain dump on paper or on a tablet?

Either works. Paper is fast and distraction-free. A tablet planner keeps the dump next to your daily pages, and with a hyperlinked planner you can jump from the brain dump straight to a task breakdown page. Use whichever one you'll actually open.

Frequently asked questions

What if my brain dump is huge and makes me more anxious?

That's common the first time. Sorting is what makes it lighter: most items end up as Later, Someday or Let go. If it's still too much, stop after the dump and only pick one N.

Should I organise the dump into categories?

Not while dumping. Categories slow you down and invite perfectionism. The four letters are enough sorting for most days.

Is there a free brain dump template?

Yes. The free Starter Kit below includes a dotted brain dump page with the N / L / S / X key, plus a task breakdown page with a "tiny first step" line.
