Why the sorting step is where ADHD planning breaks
Most planning advice assumes the hard part is remembering what you have to do. For a lot of ADHD adults it isn't. The list arrives on its own, unbidden, usually at 1am. The hard part is the next step: looking at eleven things of apparently equal urgency and deciding which three are today.
That step asks for exactly what's in short supply. You have to hold several options in mind at once, compare them against each other, imagine consequences that haven't happened yet, and then discard things — which feels, in the moment, like failing at them in advance. Executive function is the name for that bundle of skills, and ADHD makes it more expensive to run.
So the pile stays a pile. Not from laziness — from a genuinely costly operation being asked of a system that's already paying full price to keep the list in mind at all.
This tool splits those two jobs apart. Get it out of your head first, where it costs nothing to look at. Then sort what's already written down, which is a much cheaper operation than sorting what you're trying to remember.
How to use it
Dump without filtering
Everything, including the tiny things and the vague dreadful ones. "Sort out the thing with the insurance" is a legitimate line. Precision comes later; right now you're just getting it out of working memory. Our brain dump method covers this step in more depth.
Make the cut while you still can
Do this in the morning, or the night before — not at 2pm. A decision made once, early, is one you don't have to re-make later when you have less left to make it with.
Give the three a rough size
Not a schedule — a size. Thirty minutes or ninety changes what a realistic day looks like. If your three add up to six hours, that's worth seeing before the day starts rather than at 4pm.
Print it and put it where you'll see it
A sheet on the desk doesn't need unlocking and has no notifications on it. This is an argument about friction, not a proven clinical effect — if you plan well on your phone, plan on your phone.
Why three, and why that's arbitrary
Three isn't a researched number and I'm not going to pretend it is. You'll find advice recommending one, three, six and "eat the frog" first — none of it with much behind it for ADHD adults specifically.
What three does is force a decision. A list of twelve isn't a plan; it's the pile again, retyped. The value isn't in the number — it's in having a cap low enough that you can't dodge the choice. If four works for you, use four. The tool will let you, and it'll tell you that you did.
The one thing worth knowing: people systematically underestimate how long their own tasks will take, a well-documented bias in the planning literature known as the planning fallacy. That isn't an ADHD finding — it shows up in everyone. It's just that if you also lose time to time blindness, an optimistic estimate and a poor sense of elapsed time compound into a day that ends with nothing crossed off.
That's the whole argument for putting a rough number next to each item: not accuracy, just a chance to notice that three "quick" things added up to five hours.

DOI 10.1037/0022-3514.67.3.366 — the source for the claim that people underestimate their own task completion times. Worth knowing: this is a general finding in undergraduate and adult samples, not an ADHD-specific one. I cite it because it is well established, not because it says anything about ADHD.
