This document provides an excerpt from the book "42 Rules for 24-Hour Success on LinkedIn" which discusses establishing clear goals and understanding how to use LinkedIn effectively. The excerpt focuses on answering why someone joined LinkedIn and what goals they have. It notes that for many people, answering why they joined LinkedIn elicits silence, and their goal was simply to sign up after receiving an invitation. However, LinkedIn is a tool that can be used to find and be found by people, communicate, help one's business or career, and more. It stresses that LinkedIn alone is not magic and success requires using it as a connector and conduit with a clear strategy and action plan.
