A reasonable perspective is that a schedule is a way of planning energy expenditures during a particular allotment of time to enable one to accomplish those activities or goals that are desirable. A reasonable person is always in control of the schedule. The schedule never controls the person because, after all, it was the person who developed the schedule and set the priorities for energy expenditure. If the priorities change the schedule should also change. A schedule is much more than a list.
Lists name things.
Schedules identify activities and provide a time framework for the accomplishment of those activities. Schedules are not to be overly detailed. If you go through all of the detail needed to accomplish a particular task when developing a schedule your energy might have been more effectively used in the accomplishment of that task rather than in the development of the schedule. A schedule is a general outline of when you plan to involve yourself in particular activities. If you develop an overly detailed schedule that accounts for all 168 hours in the week you will probably be very frustrated at the end of the week because you made mistakes in your planning of an activity or in the implementation of a task or guessed wrong in your estimate of task duration.
