Why Two Open Projects Wreck Both of Them
You've got two projects going. Not two random tasks — two things you actually care about, half-built, sitting open somewhere on your desk or your desktop right now. You tell yourself the problem is focus. Find a way to shut out the noise, and you'll finally push one of them through.
Here's the uncomfortable part: the noise probably isn't the thing pulling you off course. You are.
Mary Czerwinski, Eric Horvitz, and Susan Wilhite ran a week-long diary study of information workers back in 2004, tracking every time someone dropped one task to pick up another. About 40% of those switches had no external trigger at all. No ping, no calendar alert — the person just decided, mid-task, to go check on the other thing. No one interrupted them. They interrupted themselves.
That number isn't ADHD-specific — it's just how attention works when more than one open thread is available to it. But if you've got ADHD, you already know which way this cuts. A brain that runs hot on novelty doesn't need a notification to go looking for something newer. The second project sitting there, half-finished, IS the notification.
Why does structure matter more than switching?
Here's where it gets more useful than "stop getting distracted." A 2011 study out of the University of Tübingen (Gawrilow, Merkt, Goossens-Merkt, Bodenburg & Wendt) put 45 men with ADHD and 42 without through a multitasking task, testing not just whether they could juggle, but how the juggling was arranged. Some conditions had them finish one block of work before starting the next. Others had the two threads interleaved — a bit of task A, a bit of task B, back and forth.
The ADHD group didn't do worse at multitasking itself. Raw performance on the split-attention work came out roughly even with the comparison group. What separated them was the structure: they did measurably better in the blocked condition and worse in the interleaved one. When they finished one block before starting the next, the ADHD group performed like anyone else. The gap only opened up once the two threads were held open together, interleaved back and forth.
That's the part worth sitting with. The structure of two live, open projects is what your brain handles worse than most, and it's a structure you're choosing, one browser tab and one open notebook at a time, usually without noticing you chose it.
What "closing the other one" actually looks like
The fix is making only one project physically live at a time, not building a bigger willpower budget for staying on task.
Pick which project gets the next block of hours. Then close the other one — really close it. Not minimized, not "in the other tab I'll just glance at." The notebook goes on a shelf, the folder gets quit. The browser tab doesn't get to linger in the background pretending it's closed. If it's visible or one click away, it's still open, and an open project is a standing invitation to self-interrupt the moment the current one gets hard.
The urge to jump won't disappear just because the tab is closed — that's not how any of this works. What changes is what you do with the urge. Keep a single small notepad next to you, not for the project itself, just for the stray thought: "check the budget sheet," "email that vendor back," "the other idea I want to try." Write it down the instant it shows up, then let it go. You haven't lost the idea. You've just refused to let it hijack the next twenty minutes.
This is different from a to-do list and different from a project plan. It's a pressure valve for exactly one thing: the mid-task urge to go check on the other open thread. Give that urge somewhere to land besides your attention, and the switch stops being automatic.
One project per sitting
None of this means you can only care about one thing at a time, or that the second project has to sit untouched for weeks. It means each sitting — each block of real working time — belongs to exactly one of them. Tomorrow the other one gets its turn — open again, live again — with today's project shut down the same way.
That's a much smaller ask than "pick a project and abandon the rest." It's also what the research actually backs: one live thread beats two competing for the same narrow lane, and that has nothing to do with trimming your project list or gritting your teeth harder.
Next time you catch yourself mid-task, reaching for the other project's tab, don't file it under distraction — that's the choice happening in real time. Write down whatever pulled at you, then get back to the one thing that's actually supposed to be open.
