How important is time? Very Important!
If time is not manage to complete a task, the expectation disappears and it becomes an empty statement.
If the 'To-Do' statement can not be made that describes a realistic expectation of a time frame and its cost expectation. A line of committed activity can not be accurately supported for completing even its rudimentary formation.
It should be understood that same requirement of time management can be applied to realistic To-Do Statements, Objective Statements, Goals and even the Mission Statement.
