It should be easy to see why the 80/20 principle is important for time management. If you compare people who are successful with those who are not, you will often find that the unsuccessful people spent most of their time working on tasks that made up the 80 percent. They didn’t put an emphasis on things that made up the 20 percent, or they didn’t work on them at all. On a personal level, you may be wondering what things make up the 80 percent. The things that make up the 80 percent are dependent on your goals. Generally, they may include watching television, talking on the phone, going to parties or clubs, or doing anything else that is not related to your goals.
