The Pareto Principle, the Eighty-Nine Rule

The pareto principle, the eightyn 20 rule. Can you think of any other ways to apply it to productivity itself? I mean, like, i sort of apply a lot to preparing for exams because often it is the 20 % of cor content that actually contributes to 80 % of the marks. And most of the way there is all you really need. You want to start off by filling that canvas as much as possible. Yerord, the broad brush strokes. Ye, another parts we fill a little bit more detaild.
