3. 80/20 rule

Let us first explain what we mean by 80/20 rule. The percentage teaches us to focus on the most important part of the assignment. If you know how to accomplish 20% of your work, you are sure to receive 80% of the desired result. To make your task less tedious, divide it into smaller parts and do the least important aspects after you are done with those that seem essential. And always remember that doing 20% does not guarantee you all 100% of the result.
