Tasks that fall under the 20 percent are things that many people usually don’t like doing. However, it is this 20 percent that will play the most important part in your success or failure. Examples of general things which make up the 20 percent are doing taxes, market research, studying, or practice. While these tasks may be boring to many, they are the factors that will play a role in your success or failure. People who are successful will spend most of their time focusing on the 20 percent of things that really matter, and will not place their main energy on things that make up the 80 percent.
