Remember the 80/20 Rule and know what the key 20 percent is. 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.) Understanding this rule saves you from getting bogged down in unnecessary detail once you’ve gotten most of the learning you need to make a good decision.
