Four parts, in the order you use them
The page follows a brain dump from a full head to a small plan.
Lined space for every thought: tasks, worries, ideas and errands, one per line, unsorted.
One box for the one thing you'll do today. If you finish it, pick another.
A few things that belong to a day this week, each with its day beside it.
What you're choosing not to do, for now or for good. Writing it down is a decision.
How to use it in five steps
About 10 minutes, with a pen or a stylus.
The full guide to doing a brain dumpWrite the date, then set a timer for 10 minutes
A limit keeps it from turning into a project. If you need longer, take it.
Fill "Everything on my mind" without sorting
One thought per line, in the order it arrives. Don't decide where anything belongs yet.
Pick one thing for today
Choose what would make today lighter, or what has a real date. Write it in the box.
Give a few things a day this week
Only what really has a date, like a call before Friday. Write the day beside each one.
Let some things go, and keep the page
Cross out what you're choosing not to do. Keep the page where you'll see it tomorrow.
The same steps on a board
Bloomingo's braindump is one board with no date. Put a thought there the moment it shows up. Give it a day later, move it to a project, or leave it. Thoughts you haven't opened for weeks fade, and Bloomingo never deletes them.
