Time management tasks can be split into urgent and important. To help you in sorting them you can use a matrix system.
The definitions:
Urgent tasks are deadline based. This is usually independent of yourself and is often driven by others. The sooner the task needs completion the More urgent it is. This has no relation to importance.
he importance of a job drives how much 'time' you want to spend on it.
Highly important and urgent tasks should be pretty rare.
