Choose one task for the block
A focus block works best when the intended output is clear. 'Study' is vague; 'draft the answer outline,' 'practice ten pronunciation items,' or 'debug this function' is easier to evaluate.
Reduce avoidable switching
Prepare the material first, close or mute nonessential interruptions where practical, and separate unrelated messaging or admin work. The aim is not perfect silence; it is fewer preventable switches during the chosen task.
Use a manageable duration
The historical source proposes particular focus intervals in places. DEPTH-01 does not turn those examples into a universal prescription. Choose a duration that fits the task, environment, accessibility needs, health, and current capacity, then review whether it was workable.
Review interruption as data
At the end, note what broke attention: unclear task, missing material, fatigue, notifications, another obligation, anxiety, boredom, or something else. Do not turn one distraction into a character judgment. Change the setup where possible.
Reflection
Questions to sit with
- What one output should exist when this block ends?
- Which interruption can I remove before I begin?
- Was the planned duration actually workable?
