A transition is two hard things in a row
Moving from one task to the next asks you to do two things: stop what you are doing, and start something else. For many people with ADHD both are expensive on their own. Stopping is hard when you are absorbed — the state often called hyperfocus. Starting is hard because of task initiation, the gap between knowing what to do and actually beginning it.
A transition stacks them. That is why the switch from deep work to a meeting, from a meeting back to work, or from work to dinner can feel disproportionately difficult — and why a day with many switches can be exhausting even if none of the tasks were.
Why it is not just "being bad at time"
Shifting attention from one task to another relies on executive functions — the brain's management system for planning, switching and holding information in mind. These are commonly described as an area of difficulty in ADHD. Add time blindness, where the next appointment feels abstract until it is suddenly urgent, and transitions arrive as a jolt rather than something you can prepare for.
Many people also describe "waiting mode": with an appointment later in the day, they cannot settle into anything beforehand, and the hours before it are effectively lost. It is not laziness. It is the brain treating the upcoming switch as the only thing that matters.
None of this is a diagnosis or a medical explanation — it is how a lot of people describe their experience. If it sounds familiar, the strategies below tend to help regardless of the label.
Make transitions visible in advance
A switch that arrives without warning is the hardest kind. Give yourself a heads-up: an alarm ten minutes before the end of a block, then another at two minutes. The first lets you find a stopping point; the second tells you to actually stop. A visible countdown timer does the same job continuously.
Warnings work because they turn the transition from an interruption into a planned event. You get to finish the sentence, save the file and park the thought, instead of being ripped out mid-task.
Leave a breadcrumb before you switch
Before you stop, write one line: what you were doing, and the very next step. "Fixing the login test — next: check the token expiry." It takes twenty seconds and does two things. It quiets the part of your mind that keeps holding on to the unfinished task, and it makes coming back far cheaper, because the next start is already decided.
Stopping at a clear next step, rather than at a neat finish, can even make the restart easier. Writers have used the trick for a long time: end the day in the middle of something you know how to continue.
Use a transition ritual
A short, repeatable ritual between tasks gives the switch a shape: stand up, refill your water, take three slow breaths, look out of a window, then read the first line of the next task. Two or three minutes is enough. The point is that the ritual is the same every time, so your brain learns it as the bridge from one mode to the next.
Movement helps especially. A short walk, even to the kitchen and back, marks the end of one thing more clearly than clicking to a different window ever does.
Have fewer transitions
The most effective strategy is often the least glamorous: reduce the number of switches. Batch similar tasks together. Cluster meetings into one part of the day instead of scattering them. Give whole days a theme where you can. Every transition you remove is one you do not have to manage.
Build buffers too. Back-to-back appointments leave no room for the stop-and-start cost; ten minutes between them often decides whether the next one goes well.
Plan around waiting mode
If an appointment at 3 p.m. eats your whole morning, stop fighting it and plan with it. Put the appointment at the start or end of the day where possible. Fill the waiting time with low-stakes tasks that are fine to drop — admin, tidying, a walk — rather than expecting deep work. And set an alarm for when to leave, so your brain can stop guarding the clock.
