The famous American hedge fund billionaire Ray Dalio made this brilliant post about the 20/80 Rule which is also sometimes called the Pareto Rule or the Pareto Law:
The 80/20 Rule
The 80 20 Rule states that you get 80 percent of the value out of something from 20 percent of the information or effort. (It’s also true that you’re likely to exert 80 percent of your effort getting the final 20 percent of value.)
