Time Boxing

Time boxing is setting a fixed, pre-committed time budget for a task and stopping when the box ends.
Unlike general time blocking (reserving calendar space), boxing adds a hard limit, which reduces Parkinson's Law, perfectionism and decision drift.

A simple loop is: Define a concrete outcome and "good enough" criteria, choose a duration, start a timer, work without switching, then stop and review.

Boxes can be chained with short breaks and calibrated over time for accuracy.
It creates momentum, protects focus and makes progress measurable even on open-ended work.
Time boxing pairs really well with weekly planning.
