Sticking to a time-scheduling system can’t guarantee the return of your longlost vacation days, but by regularly tracking your meetings, appointments, and obligations, you reduce your odds of double-booking and scheduling appointments too close. And by planning ahead, you make sure to make time for all the important things first.
The system ensures that you put your priorities first (starting with routines and then moving to individual tasks/activities) before scheduling in commitments and activities of lesser importance. Such time-management techniques are just as applicable to the other spheres of your life. There’s a reason why I advise you to plug in your personal commitments first when filling in your time-blocking schedule: Your personal time is worthy of protection, and you can further enhance that time by applying time-management principles.
