Batch

Corral tasks into themed time-block batches and stop context-switching. On-device.

Context-switching is the tax nobody budgets for. Every jump between unrelated tasks leaves part of your attention behind on the last one, and the cost is largest for work that took effort to load into your head in the first place.

Batching is the countermeasure: group similar tasks and do them in one block, so you pay the setup cost once instead of six times. Batch organises work into themed time blocks rather than a flat list, which means the decision you make is which block am I in rather than what next — a much cheaper question to answer forty times a day.
