Build a More Realistic Work Block by Counting Breaks
Separate elapsed time from focused time so plans survive interruptions and handoffs.
An eight-hour window rarely contains eight hours of focused work. Meetings, messages, setup, and breaks all consume time. Planning with that reality produces clearer estimates and makes it easier to explain why a task needs another day.
Reserve time for the work around the work
Include setup, review, and handoff time rather than counting only production. Break a task into a first visible deliverable, then give yourself a short block to check it before calling it finished.
Use the record to improve the next estimate
After a few sessions, compare planned and actual focus time. The purpose is not surveillance; it is to learn where a plan was optimistic and what should change next time.
