Calendar time blocking

Give every task a specific start and end time on your calendar.

Why it works

Assigning a task to a time slot converts an open intention into a pre-commitment with a cue, which is far more likely to be acted on than an undated list item. It also makes scarcity visible: when the day is full, you must consciously trade, instead of pretending everything fits.

How to do it

1. At the start of the day or week, place each task into a concrete calendar block.
2. Block protected time for important work before meetings fill the gaps.
3. When a block runs over, re-block the rest of the day rather than abandoning the plan.

Evidence

Time blocking operationalizes implementation intentions (specifying when and where a task happens), which have strong meta-analytic support for improving follow-through. (rct)

The implementation-intention evidence is robust; that the full calendar-blocking system outperforms a good list is plausible but not directly trialed.

Common mistake

Building a flawless plan and then abandoning it the moment one block slips, instead of re-blocking. The skill is dynamic re-planning, not perfect prediction.
