A stolen hour is easy to notice. What actually disappears from most days is smaller and quieter, a notification here, a “quick” check there, none of it registering as a loss on its own. This one-page worksheet makes that pattern visible for exactly one day: a simple tally sheet, carried with you, plus a short read on what the numbers usually mean once the day is over.
Inside: a tally table for every source of interruption, a place to note when they clustered, and a short guide to reading your own results before you decide what to isolate against.
