Doing one thing at a time
Doing one thing at a time means giving a single task your attention until it is done or you deliberately stop, instead of switching between many. It is harder than it sounds, especially with ADHD, because everything competes for attention at once. The fix is usually not more willpower but fewer visible options.
Why switching costs so much
Every time you switch tasks, a bit of attention stays stuck on the one you left, so you are never fully on the new thing. Those open loops pile up, and for a brain that already struggles to hold things in working memory, a screen full of half-started tasks is exhausting rather than productive.
Make the current thing the only thing
You cannot force focus, but you can remove competition for it. A few things that help many people:
- Show one task, not the list. Put the thing you are on where you will see it and hide the rest until it is done.
- Time-box it. Agree to stay on it for one short block, then decide. A boundary makes staying easier than an open-ended stretch.
- Body double. Working next to someone, in person or on a call, borrows their steadiness and makes wandering off more obvious.
Where NanoDo fits
NanoDo is built around showing one thing. Your focus task sits on your lock screen, so the current thing is the thing you see, and the rest waits out of view. It is one way to make single-tasking the default, not a treatment, and not the only way; a single sticky note works too.
