An important way to set the priority order of the work is to separate the emergency tasks with important tasks:
Effective and important things are what you have to take action immediately, and your work is depends on this task. I can't complete an emergency and important task, and the consequences may be serious.
Important, not an urgent task is usually the task you can temporarily delay. In the long run, these are also the task capable of producing major consequences, perhaps positive, perhaps negative.
For example, drafting a key report, sticking to a learning process, spending time with them in the child's growth. You can delay these activities in the future, and you usually do this.
Urgent but unimportant tasks include calling for colleagues who want to talk to you and collect mail. These tasks are very urgent, but from the consequences, they are not important. It is neither important thing that is not an urgent task is a waste of your time, especially when they reduce your more effective activities.
The key to efficient work is to first focus on all urgent work, followed by focusing on important but unopened activities. At the same time, you must postpone, extension, delegate and terminate all other things. You must resume yourself, stop the urgent but not important things, and those who are neither an urgent need.
