Frequently Asked Questions

Divide time spent by total time, multiply by 100. Example: 3 hours into an 8-hour workday: (3 / 8) × 100 = 37.5% elapsed, 62.5% remaining. For dates: use days between dates.

Track time on each activity, divide by total time. Working 8 hours: 4 hours on project A = 50%, 2 hours on meetings = 25%, 2 hours on emails = 25%. Helps identify time drains.

The Pareto Principle: 80% of results come from 20% of efforts. Identify your highest-value 20% activities and allocate more time to them. Example: 20% of clients generate 80% of revenue.

Set target time allocations (40% deep work, 20% meetings, 20% communication, 20% admin), track actual time spent, compare to targets. Adjust schedule to align with goals. Review weekly.
