Focus on the most minor details while completely overlooking the main topic.
Do several completely unrelated things at the same time, ensuring nothing gets done efficiently.
Read an entire book on a tangential topic while pretending to be working on the main project.
Engage in lengthy conversations with coworkers to "get to know them better" and "build relationships" while completely avoiding actual work.
These tactics are highly effective and may be employed in various situations. However, please use them responsibly.
