Encontré un blog que habla sobre esto. Extraigo algunos párrafos que me parecen interesantes.
The Pareto principle (also known as the 80-20 rule and the law of the vital few) states that in many things, 80% of the consequences come from 20% of the causes.
How can we put the 80-20 principle to good use?
The Pareto principle is great to increase focus. Don't try to do more. Just do more of the right things. For example, out of our many maladaptive behaviors, twenty percent of it will contribute to 80 percent of all our hardship and misery. So working on just these 20 percent can greatly contribute to our personal growth. Time management is another area where the rule can be very effective. If you have a lot of work to do, break it down to specific activities and figure out what twenty percent of the tasks listed contributes to eighty percent of the results you seek. Second, give your maximum concentration to those 20 percent tasks.
So how do you know if you're working on the twenty percent that really matters?
It makes you feel good because you are doing what you always wanted or you know it'll help with your goals.
You are doing the tasks that you'd like to procrastinate, but know that it is essential.
You delegate tasks to others that you aren't good at.
You are doing something that uses your creativity
