Your classmate is the secretary of the Political and Legal Affairs Commission, and you're a food delivery driver—that's not a network. So what is a network? You're a food delivery driver, and your classmate is a security guard at a residential complex—*that's* a network. You can tell him which restaurants are the cleanest, and you can even bring him lunch every day at noon; he can let you into the complex. You each provide value to each other—*that's* what a real network is. Networks aren't something you pursue; they're something you attract.
