Time blocking reserves your calendar
Block specific hours for work types (deep work 9-11am, meetings 1-2pm). This prevents context switching and protects focus time.
Time boxing constrains task length
Set a fixed duration for a specific task (30 min for emails, 45 min for design). This creates urgency and prevents scope creep.
Combine both for maximum clarity
Use time blocking for calendar strategy and time boxing within each block to keep momentum high.
