The Pareto Principle: Work Less, Achieve More

The Pareto Principle, or the 80/20 rule, states that for many phenomena 80% of the result comes from 20% of the effort. The principle has been named after Vilfredo Pareto; an Italian economist who, back in 1895, noticed that about 80% of Italy’s land belonged to 20% of the country’s population.
Although originally the Pareto principle referred to the distribution of wealth, it can be applied to a wide variety of contexts. Some cool examples:
~20% of seeds planted result in ~80% of the flowers.
~20% of the world has ~80% of the wealth.
You wear ~20% of your clothes ~80% of the time.
In fact, The Pareto Principle comes also in handy in the setting of time management.
Once you realize that 80% of your outcomes come from 20% of the time and effort you spend on them, the importance of prioritizing becomes obvious.
For instance: if you have a 10-item to-do list with each task being equally
time-consuming, you can boost your efficiency by identifying and completing two top-priority tasks. As a result, even if you don’t manage to do all the remaining tasks, the 20% you completed could amount to up to 80% of the impact.
What if this rule can be applied to academics?
