Time is Not a Resource. Time is nothing more than a measurement of intervals. It is not a resource. A resource can be used and manipulated in many ways - borrowed, traded, saved, bought and sold, stockpiled for later use. But time cannot be saved.
All time is current time.
No one can save it, put it in a time bank and keep it for future use. Many of you have probably been to classes on time management, hoping that time is a thing to be managed. Now you find that it is yourself that must be managed. And managing yourself is all about setting priorities - something in which planners claim to be skilled. No one ever has enough time.
