‘I’ll do it later’ is a lie your brain believes every time

Future you feels like a different, more capable person. She is not.

The short version: try one today

• If it takes under two minutes, do it now.
• If not, give “later” a real time and an alarm.
• Leave a visible reminder in your path, like the item by the door.

Stuck at the starting line right now? Priori breaks the task into tiny first steps, so you only have to do one. (We make it. It's free to download.)

Your flatmate texts asking you to transfer your share of the electricity bill. You read it, think “I’ll do it later” and mean it completely. Nine days pass. For anyone stuck in the ADHD I’ll do it later loop, the strange part is how sincere the promise feels every single time.

You meant every word. The job simply got handed to a version of you who seems rested, organised and oddly free on Thursday. She never turns up.

Why later feels like a real plan

Many people with ADHD describe time as having two settings: now and not now. Anything in “not now” goes blurry. It has no weight and no slot, so it doesn’t feel like a job waiting. It feels like a job handled.

Working memory makes it worse. The moment you look away from the text, the task drops out of your head. Nothing in your day will bring it back unless something outside you does. That’s a big part of time blindness.

And future you gets imagined generously. She has energy. She likes admin. In reality she’ll have the same brain, the same tiredness after work and her own pile of things past you left behind.

Under two minutes: do it now

If the task takes less than two minutes, do it while it’s in front of you. Transfer the money. Reply “yes, Saturday works”. Put the plate in the dishwasher. Hang up the towel.

Storing a task costs more than you’d think. You have to remember it, come back to it and start it from cold, and each of those is a known ADHD weak spot. For tiny tasks, doing is cheaper than storing.

One warning. Two-minute tasks can chain together until you’ve spent an hour on small stuff and missed your lecture. If you were in the middle of something important, jot the tiny task down and go back to what you were doing.

Giving ADHD I’ll do it later a real time and an alarm

Bigger tasks can’t all be done on the spot, so “later” needs an address. Say when: “Wednesday at 6pm, after dinner.” Then set an alarm and label it with the action, something like “Renew railcard, card is in purple wallet”.

• Vague: “I’ll book the dentist this week.”
• Real: “Thursday 12.30, lunch break, alarm set, number saved in my phone.”

A time without an alarm is still a wish. You won’t notice 6pm arriving on your own, so let a phone reminder or a calendar alert do the noticing.

When the alarm goes off and you truly can’t do it, don’t swipe it away. Move it to a new specific time. Snoozing three times is fine. Dismissing it sends the task straight back into the fog.

Put it where you’ll trip over it

Alarms can be ignored. Objects in your path are harder to miss. The parcel to return goes in front of the door, so you’d have to step over it to leave. The form to sign sits on your laptop keyboard. The library book goes next to your keys.

This works because your memory no longer has a job to do. The world reminds you. It’s the principle behind putting your brain outside your head.

It stops working when the object sits there long enough to become furniture. If you’ve been stepping over the parcel for a week, move it somewhere more annoying, like on top of your shoes.

Many women with ADHD describe carrying a huge invisible list of these small laters, alongside everyone’s birthdays and whose turn it is to buy bin bags. Getting each one out of your head and into an alarm or a doorway makes that load a bit lighter. You’ll still say “later” sometimes. Try to say when.

Quick questions

Why do I always say I’ll do it later with ADHD?

Many people with ADHD experience time as either now or not now, so a task pushed into the future stops feeling real. Working memory then drops it as soon as attention moves on. Saying “later” feels like a plan, but without a set time and a reminder there’s nothing to bring the task back.

Does the two minute rule work for ADHD?

Doing very short tasks straight away helps many people with ADHD, because it removes the need to remember and restart them. The catch is that small tasks can snowball and pull you off something more important. If you’re mid-task, write the small thing down and return to it afterwards.
