2. Add fixed commitments
Include meetings, classes, appointments, or travel blocks that cannot easily move.
3. Reserve focused work
Enter the time needed for the most important concentration-heavy work.
4. Add routine work and breaks
Include administrative tasks, recurring chores, meals, and recovery time.
5. Review the remainder
Use positive open time as buffer; reduce or move work when the plan is overbooked.
