Time blocking is easy to plan but harder to execute honestly. Without measurement, many blocks include more switching and interruptions than we think.

This is where the stopwatch tool becomes useful. It makes focused sessions visible in real time, which helps you compare the schedule you intended with the work you actually completed.

Run the stopwatch only during active focus, pause when interrupted, and note what caused breaks so you can improve future blocks.

A good workflow is simple: open the tool, test your input, review the output, and make small improvements before sharing or saving the result. Track three blocks a day for a week and compare planned versus actual time.

Do not treat a scheduled hour as an automatic hour of deep work. Real focus needs evidence, not assumptions.

The best results usually come from consistent small improvements rather than one perfect attempt. Measure what works, keep what is useful, and repeat the process the next time you need the tool.
