Single handling
Start the most important task and stay with it, without switching, until it’s 100% done.
Why it works
Switching away from a task leaves attention residue that degrades the next task and forces a costly reload when you return, so a task touched repeatedly takes far longer than one done in a single stretch. Single handling captures that efficiency and delivers the psychological lift of actual completion rather than perpetual half-done work.
How to do it
- Once you start your top task, close everything unrelated to it.
- Resist the urge to "quickly" handle anything else until it’s finished.
- Treat partial completion as not done — return to it before opening a new task.
Evidence
Supported by research on attention residue and task-switching costs, which show that interrupting and resuming work reduces speed and accuracy on the resumed task. (observational)
The switching-cost evidence is robust; "single handling to 100%" is a practitioner application of it.

Common mistake
Leaving a task at 90% to chase a fresher one, accumulating a pile of nearly-finished work that each carries a restart cost.
