1. Assess Available Time – List the hours available each day for work, rest, meals, and other activities.
2. Set Priorities – Determine what activities are most important, such as sleep, meals, exercise, and work responsibilities.
3. Allocate Time Blocks – Assign specific time slots to different activities, ensuring that she leaves enough time for sleep and relaxation.
4. Include Breaks – Plan short breaks during work to avoid fatigue and improve productivity.
5. Review and Adjust – Evaluate her plan after a few days to see if it’s working well and make necessary adjustments.
