Paolo Beffagnotti. Prior to the chat for time management, may be we could add on this chat.
It is importantto start with setting a daily goal and the goal of each activity as a guideline so that we know which to prioritize. What do you think?

Just would like to summarize the discussion.
1.Time management is more than just managing time
2.Correct goals setting is important
3.Use Eisenhower matrix to manage oneself in relation to time by setting priority by taking charge of the situation and optimize time utilization
4.Change habits that are either waste of time or non productive. Basically = Eliminate it!

In some ways yes. However, with agile project plans this is kind of sorted. In Agile, "Eliminate" can be considered as lowers priority task.

The chart could be further simplify into do first and do later. If one could just sort out their daily activities into urgent and not urgent stuff, they are able execute their daily activity efficiently to progress smoothly in their life.
*This is because sometime it is difficult for some to sort out stuff that are important or not important. It might be not important for one but important for others.**

Time is the most important commodity we have. A key aspect of management is knowing what not to do. As previous respondents have said, there are many 'versions on a theme' to the original matrix. I would add 'mission critical vs non-mission critical' as a further option to prioritise tasks.

Yes Paolo Beffagnotti, this is one of the management basics, but it is always good to remind, especially under pressure...

I've seen situations where people have been rewarded for 'fire fighting'. Further questioning suggests that these people created the fire in the first place.
Why plan a sensible use of one's time if 'panic mode' gets more attention?
