The ABC Method is a strong technique for daily communication. This technique is so simple and effective that it can make you one of the most efficient and effective in your field.
The technique works like this: You start with a list of everything you have to do for the coming day. Then, you place an A, B, or C before each item on your list before beginning the first task. A means something really important, top priority task. B is secondary important tasks. According to the rule, you can never do B, if A is not finished yet. C considers something not important as A and B. There are no consequences whether you do it or not.
