Minimalist lifestyle is a lifestyle that follows "subtraction" and eliminates complexity, such as removing some boring social interaction, unnecessary interpersonal communication and redundant work. Only by eliminating complicated tasks can we highlight some decisive key tasks and devote our limited time and energy to these tasks. A prerequisite for getting rid of clutter is that there should be one or several clear central goals in a specific period of time, and one can simplify one's desires and constrain one's behavior to act around these goals. People who have a central goal but are not good at restraining themselves are also easily drawn by various temporary interests, lost in the sea of Wang Yang where Wang Yang pursues interests, and ultimately accomplish nothing. For example, some people go online to inquire about a specific information, but they are constantly attracted by other contents on the webpage and wander from one point to another. As a result, they unconsciously wasted a lot of time, but still failed to complete the original task.
