How to stop being late
Last updated 5 August 2026 · 6 min read
Chronic lateness gets treated as a character problem — disorganised, inconsiderate, not trying hard enough. It rarely is. Almost everyone who is reliably late is making the same specific measurement error, and once you see it, the fix is mechanical.
The error is this: you remember journeys by their best-case duration, and you time them from the wrong start point. The drive is 25 minutes, so you leave 25 minutes before. But the journey was never 25 minutes. It was 6 minutes of finding your keys, 25 to 40 minutes of driving depending on the hour, 4 minutes of parking, and 3 minutes of walking to the right door. You planned for the middle third and were surprised by the rest.
The seven fixes, in order of leverage
These are ordered by how much time each one recovers. If you only do two, do the first and the last.
1Plan backwards from the arrival time
Start at the time you must arrive and subtract every segment: the meeting buffer, the walk from parking to the door, the drive, and the time to get out of your house. The answer is your leave time. Most people plan forwards from now, which quietly ignores everything except the drive.
2Measure your real door-to-door time
Time one trip properly, from standing up to sitting down at the destination. Almost everyone's real number is 10 to 20 minutes longer than the figure a maps app quotes, because maps time the drive, not the journey.
3Add a fixed buffer and never negotiate it
Pick a buffer once — 10 minutes for local trips, 20 for anything unfamiliar — and treat it as part of the travel time rather than a bonus you can spend. Buffers only work when they are not up for debate in the moment.
4Front-load everything you can do the night before
Keys, bag, clothes, fuel, and the destination address all get decided the night before. Every decision left for the morning is a chance to lose five minutes.
5Set the alarm for leaving, not for the event
An alert that says '3pm meeting' arrives too late to be useful. The alert you need says 'leave now', which is a different time on a different day depending on traffic.
6Kill the one-more-thing habit
The last task before leaving is the one that makes you late. Once your leave alert fires, the rule is that nothing new starts. Whatever it was will still be there when you get back.
7Automate the calculation entirely
The steps above all depend on you remembering to do them. Handing the calculation to an app that watches live traffic and your calendar removes the last failure point: Can't be Late computes your leave time continuously and pushes a notification at the right moment, so punctuality no longer depends on you checking anything.
Why willpower-based fixes keep failing
Every technique on the list except the last one has the same weak point: it needs you to execute it correctly while you are busy, distracted, and mid-task. That is precisely the condition under which time estimation is worst. You are asked to make a careful judgment at the exact moment you have the least attention available for it.
Setting a calendar reminder for the event doesn't help either, because the event time is a constant and your leave time is not. A 9am meeting needs a 8:15 departure on a clear Tuesday and a 7:50 departure when the highway is backed up. A static reminder cannot know the difference. That is the gap live-traffic departure alerts exist to close.
What about time blindness and ADHD?
If you struggle to feel elapsed time passing — a common experience with ADHD, often called time blindness — internal techniques are the least likely to work for you and external cues are the most likely. You are not going to fix this by trying to sense the clock harder.
What works is moving the timekeeping outside your head entirely: an alert that arrives on its own, at the right moment, without you having to remember to check anything. This is the reason a push notification outperforms a mental rule for most people, and dramatically outperforms it for people with time blindness. More on the underlying causes here.
Common questions
How do I stop being late for work every day?
Measure your true door-to-door commute time on a bad-traffic day rather than a good one, set your leave time from that number, and add a fixed 10-minute buffer you never spend. Then move the alert from the meeting time to the leave time — an app like Can't be Late does this automatically using live traffic.
Is being late a habit or a personality trait?
It's a habit built on a measurement error. People who are chronically late are usually estimating from best-case memories of a journey and forgetting the non-driving parts of it. Change what you're measuring and the behaviour changes with it — no personality overhaul required.
How much buffer time should I add?
Ten minutes for routes you drive regularly, twenty for anywhere unfamiliar or anywhere you'll need to park and walk. The exact number matters less than making it fixed, because a buffer you renegotiate in the moment is not a buffer.
What is the fastest way to become more punctual?
Stop deciding when to leave. Every other technique still routes through a judgment call you make while distracted. Delegating that call to a calendar-aware app with live traffic data removes the step where punctuality usually fails.
