Switching tasks can leave you thinking about the work you just put down. This article uses that familiar problem as a planning prompt. It does not claim to measure attention residue or attach a precise productivity loss to every interruption.
Close the current loop on paper
Before moving away, write three things: what is complete, what remains uncertain and the next concrete action. For a spreadsheet, that might be “Totals checked; region C still needs review; compare rows 18–24 next.” Keep the note where you will resume the task.
Make the next task easy to enter
Open only the materials needed for the next action. Decide what you want to produce during the upcoming session. A bounded goal such as “draft the opening paragraph” is easier to recognize than “make progress.” If unrelated ideas arrive, put them in a short parking list and return to the chosen action.
Handle interruptions honestly
Some jobs require frequent availability. A long uninterrupted block may not fit them. Use a shorter timer, leave a clear restart note and pause when necessary. Zehano’s focus timer does not block other apps or monitor your work. A completed countdown records time passing, not verified concentration or output.
