Getting Things Doneadults
The Invisible Wall Between Intention and Action
You want to do the thing. You've decided to do the thing. And yet, somehow, the thing does not get done. Here's what's actually happening in that gap.

There's a particular kind of confusion that comes with wanting to do something, meaning to do it, having every reason to do it — and simply not doing it. Not out of laziness, not out of confusion about what's required, but because something between the intention and the first action refuses to close.
This is one of the more misunderstood parts of ADHD, precisely because it looks, from the outside, exactly like not caring. From the inside, it feels closer to standing in front of a locked door you know how to open, holding the key, and finding that your hand won't move toward the lock.
What's actually happening
Executive function research describes task initiation as the specific cognitive process of converting a decision into a starting action. It's separate from planning (knowing the steps), from working memory (holding the steps in mind), and from motivation (wanting the outcome). You can have all three of the others fully intact and still hit a wall at this particular junction — which is exactly the experience many adults with ADHD describe: total clarity about what needs to happen, full desire for it to be done, and still, nothing moves.
One useful way to think about it: the brain's initiation system doesn't run primarily on importance. It runs on interest, novelty, challenge appropriate to skill, urgency, and immediate consequence — sometimes summarized informally as the difference between what matters and what's stimulating enough to register right now. A task can be objectively critical to your life (paying the bill, making the call, starting the report) and still fail to generate enough of a signal to trigger action, because importance and stimulation are not the same currency, and ADHD brains tend to run a poor exchange rate between them.
This is compounded by working memory demands. Many stalled tasks aren't actually one action — they're a bundled sequence of decisions (open the file, remember the format, find the earlier draft, decide where to resume). When all of that arrives at once, without a clear entry point, the brain can respond to the whole tangled bundle by doing nothing at all, which then gets misread — by you and by other people — as avoidance rather than overload.
Why this can be hard with ADHD
Overwhelm and perfectionism often arrive together. If a task doesn't have an obvious clean entry point, the mind can default to waiting for better conditions — more time, more clarity, more energy — rather than beginning imperfectly. The trouble is that those ideal conditions rarely arrive on schedule, and the waiting itself starts to feel like a plan, when really it's just a very well-disguised form of the wall.
There's also a learned pattern worth naming honestly: urgency works. Adrenaline is a genuinely effective, if brutal, way to force the initiation system to fire — which is why so many adults with ADHD report doing their best work under last-minute pressure. The problem isn't that this doesn't work. It's that it works reliably enough to become the default ignition system, which means early starts, calm starts, unhurried starts become rarer and rarer, replaced by a life organized around waiting for the deadline to get close enough to hurt.
This gets more consequential in adult life because the stakes attach to things that don't forgive lateness the way school assignments sometimes did — invoices, medical follow-ups, difficult conversations with a partner, replying to an email that's now three weeks old and has calcified into something that feels impossible to address at all. The friction compounds; the avoided task doesn't just sit still, it accrues social and emotional interest.
The wall isn't a verdict on how much the task matters to you. It's a description of how your initiation system is currently wired to respond to it.
What this looks like in real life
- 01Knowing exactly what the email should say and leaving it unsent for eleven days, not out of avoidance of the person, but of the starting.
- 02Rearranging your desk, your calendar, your task list — anything adjacent to the work — before touching the actual work.
- 03Feeling real relief within the first two minutes of starting something you'd been dreading for a week.
- 04Doing your best, most focused work only once a deadline has become frightening enough to force your hand.

Make It Smaller
Most stalled tasks aren't too hard — they're too large and undefined to have an obvious first move. Shrinking the entry point, deliberately and specifically, gives the initiation system something it can actually respond to.
- 01Name the task you're avoiding exactly as it currently sits in your head.
- 02Break it down until the very first move takes under two minutes and requires no decision-making (open the document, not write the report).
- 03Do only that first move, and consider the task launched, regardless of what happens next.
- 04If momentum builds, keep going; if it doesn't, count the small start as a genuine win and return later.
The evidence
What the science says
Task initiation is treated within executive function frameworks as a distinct process from planning, working memory, and motivation, and difficulties initiating non-preferred tasks are consistently documented in ADHD across the lifespan. The 2021 international consensus statement on ADHD, led by Faraone and colleagues, frames these executive difficulties as core and neurodevelopmental rather than motivational in origin.

Building a way across, not just a way through
The most sustainable strategies tend to work with the initiation system's actual preferences rather than against them: shrinking tasks until the entry point is trivial, externalizing the first step so it doesn't rely on memory or mood, and manufacturing a milder, earlier version of urgency instead of waiting for the real deadline to supply a harsher one. None of this eliminates the wall entirely — it's a durable feature of how the ADHD brain handles low-stimulation tasks, not a bug to be permanently fixed.
What changes, with practice, is your relationship to the wall. It stops being proof of some character failing and starts being a familiar landmark — something you recognize quickly, respond to with a specific move, and get past a little faster each time, rather than a surprise you have to relitigate from scratch every single time it appears.
The distance between intending and doing isn't a measure of your commitment. It's a gap you can build a bridge across, one small, deliberate first step at a time.
