You started the spreadsheet on Monday, the cupboard on Tuesday and the online course on Wednesday, and all three are still open.
Each one was easy to start. Each one was interesting for about forty minutes. Then a newer thing came along, the old thing went quiet, and now it sits there half done, taking up room. If you have ADHD you have a drawer of these, and the drawer is heavy.
Starting was never your problem
You start well.
An ADHD brain starts on interest, novelty, challenge or urgency. William Dodson, a psychiatrist who saw adults with ADHD for decades, calls this an interest-based nervous system. It is a clinical model from years of patients, not a trial, so we say it plainly and no bigger. On day one a new task has three of the four in reach. It is new. It is a small challenge, because you have not done it before. Nobody has told you it is boring yet.
So you start, and the first hour is often your best hour on any task. The problem was never the first hour.
A half-done task is no longer new
The task you started yesterday has spent its newness.
Look at it through Dodson's four again. It is not new; you have seen it. It is not a challenge; you know how it goes now. Its deadline, if it has one, is far away. Nobody is watching. The half-done spreadsheet has none of the four things your brain starts on, and the fresh course has all of them.
An ADHD brain does not start on importance. It starts on new, and a new task starts itself while the half-done one waits. This is not a decision you made. It is the same starting rule running forwards through your week, leaving a trail of open tabs behind it.
The rule does not say you are flaky. It says the old task needs a new reason.
The nine you did not finish do not go quiet
An unfinished task keeps a hand on your sleeve.
In 2011 Masicampo and Baumeister ran five experiments on unfulfilled goals. An open goal kept pulling at people's attention while they did other things. One change stopped the pull: writing a specific plan for the goal. Not finishing it. Planning it. The people in those experiments did not have ADHD, so we say this plainly and do not make it bigger.
With ADHD there is a second layer. It is hard to keep a list in your head, and a 2013 meta-analysis of 38 studies in adults calls this well supported (Alderson and colleagues). So the nine open tasks pull at you, and you cannot hold what they are, so the pull arrives as a feeling instead of a list. The feeling is guilt. It has no item number.
Ten open tasks, ten hands on your sleeve, and none of them says its name.
A task can end without being finished
There are two endings for a task, and only one of them is finishing.
The other is deciding. The course you stopped at lesson three: will you finish it? Answer for the real next month, not the ideal one. If the answer is no, the task has an ending available right now, and the ending is a decision. Close it. Not as a failure. As a choice made by the person who knows their own week.
Most to-do lists have one exit, the tick, so a task you will not finish can only sit there as a small daily loss. Nine losses a day is how a list becomes a thing you stop opening. You were never lazy. You had nine tasks with no honest way out.
There is a third case, and it is the one people miss. The task you will finish, but not this week. It does not need an ending. It needs a plan: one next step, written down, with a day on it. The pull stops at the plan, not at the finish line. Masicampo and Baumeister's people got their attention back from a written plan, before anything was done.
The permission to close a task you will not finish is the whole point of this page. A plan quiets the pull. So does an ending.
How Kaapi does it
In Kaapi a task closes in two ways, and both tick the box.
Done is finished. Settled is closed without finishing, and the button for it says Let it go. When a task's time passes, the task says Missed in plain ink inside a thin line, and the card asks three things: New time, Done already, or Let it go. Done already is for the one you finished on Tuesday and never ticked. New time is for the one you still mean to do. Let it go settles it. The box is ticked, and nothing is counted back at you. Nothing turns red, because a red pile is the thing you stop opening.
A settled task is not gone. Bring back reopens it, so if the course calls you again in November, it is open again. Done rows leave the page four hours after closing, and ticked steps inside an open task stay where they are, so a half-done task keeps its progress in view. The page holds the open work, and only the open work.
We built two endings because we had the drawer too. One tick for finished, one tick for decided, and no count anywhere of which was which.
How to do this without Kaapi
Give every open task one of two things today: a next step or a line through it.
- Put every half-done thing in one place. Paper is fine. Count them.
- Ask each one a yes or no question: will I finish this? Answer for the real next month.
- For every no, draw a line through it and write "let go" beside it. This is an ending. It counts.
- For every yes, write the next step, small enough to do in ten minutes. A specific plan is what quiets the pull.
- Pick one yes. Do its step today. Leave the rest alone until tomorrow.
- Keep the let-go list. Read it once a month, and bring one back if it wants to come back.
If the list is long and none of it will move, the size of the list is the problem, not you. Here is what to do when the whole list freezes you. If a yes task will not start even with a next step, the step is still too big.
Frequently asked questions
Why do I start so many things and never finish them with ADHD?
Because an ADHD brain starts on what is new, and a task stops being new after the first session. The fresh task starts itself; the half-done one has spent its novelty and waits. Starting is easy for you. The second session is the hard one, and it needs a new reason: a time, a step, or someone there.
Is it OK to abandon a task with ADHD?
Yes, if you decide it. A task has two endings, finishing and deciding, and most apps only give a tick to the first. Choosing not to finish is a real ending. Write it down, draw a line through it, and let it go. The guilt was about the open loop, not about the task.
How do I finish a task I have lost interest in?
Give it one of the four things an ADHD brain starts on. A time of day you can see. A different room. Ten minutes on a clock. A friend on a call. And write the next step first, because an open task quiets down once it has a specific plan, as Masicampo and Baumeister found in 2011.
What should a to-do list do with a task I will not finish?
Give it a second exit beside the tick. When its time passes, the task should ask one plain question: new time, done already, or let it go? Letting it go should close the box, keep the record so you can bring it back, and count nothing against you. Nothing should turn red, and nothing should pile up.
