For example, once you learn the “80/20 Rule,” which states that, in many domains, 20 percent of your efforts produce 80 percent of your results, you can use this mental model to improve efficiency and impact in every area of your life as well as every field you study forever. You can identify the 20% of relationships that cause 80% of your feeling of connection. You can identify the 20% of clients that create 80% of your business. You can identify the 20% of tasks that create 80% of your productivity. And so on!
