How to do a brain dump: the 5-minute method (with example)
A brain dump is a timed, unfiltered purge of everything in your head — tasks, worries, ideas, complaints. Set a 5-minute timer, speak or write continuously without editing, then sort each item as action, question, worry, or nothing. It works because working memory is finite, and every unresolved item takes a slot.
A brain dump is a five-minute purge of everything in your head. Here's what it is, how to do one, an example, and how to sort what you find.
Frequently asked questions
What is a brain dump?
A brain dump is a fast, unfiltered transfer of everything in your head — tasks, worries, ideas — onto paper, a screen, or a voice recording. The goal is to clear working memory, not to plan.
How do you do a brain dump?
Set a timer for 5 minutes and speak or write continuously without editing. Don't filter, don't organize, don't try to finish. When the timer ends, walk away for 2 minutes, then sort each item as action, question, worry, or nothing.
How long should a brain dump take?
Five minutes is the sweet spot. Long enough to surface deeper items, short enough that you'll actually do it. Hard cap it with a timer.
When is the best time to do a brain dump?
First thing in the morning, right before deep work, or before bed. Avoid doing it right after a meeting — you'll just dump the meeting.
How do you brain dump before bed?
Do a normal 5-minute dump, but end each item with 'and I'll deal with it tomorrow.' That phrase tells your brain the item has been heard, which stops the nighttime rehearsal loop and helps you fall asleep faster.
What do I do with the brain dump afterwards?
Sort each item as action, question, worry, or nothing. Actions go on your task list. Questions go to whoever can answer them. Worries get a one-sentence contingency. Nothings get deleted.
Is it better to type, write, or speak a brain dump?
Speaking is fastest and tends to surface the most because it matches the speed of thought. Writing by hand slows you down enough to feel more thoughtful. Typing is in the middle.
