Building real professional relationships, rather than a contact list you activate when you need something.
Professional relationships are how most work actually moves — how you find out what's really happening, who to ask, what a role is like before you take it. "Networking" has a bad reputation because the version most people have seen is transactional: contact collection, then extraction. The version that works looks unremarkable from outside. You stay in touch with people whose work you find interesting, you help when you can do it cheaply, and the relationship is real enough that an ask, when it eventually comes, isn't the first message in two years. Most of it is deposits made long before any withdrawal, which is why it can't be started in the month you need it.
Reappears in your inbox after twenty-two months of silence with a warm paragraph about how much they've valued your work, followed by the ask. The pattern is so consistent that recipients now recognize it from the opening line and read the rest to find out what it is this time. Would be genuinely hurt by the suggestion that this is extractive, having never noticed that every message in the thread was sent by them and preceded a request.
Optimizes the conference for coverage, achieving forty conversations of ninety seconds each, and returns with a contact list of people who would not recognize their name a week later. Counts the list as the outcome. Has confused the artifact of a relationship with a relationship, and has forty of the former, which combine to produce roughly the value of none of the latter. Will attend the same conference next year with the same strategy and a slightly larger list.
Invests exclusively upward, on a reasonable-looking theory about where influence sits. Is attentive and generous with anyone two levels up and briskly efficient with peers and juniors, who notice. Discovers over a decade that the peers became the senior people, the juniors became the hiring managers, and the relationships that would have mattered most were the ones being triaged out on grounds of insufficient current seniority.
Is asked to connect two people who would obviously benefit from knowing each other, and does not, without ever quite deciding not to. The introduction stays perpetually about to be made. Preserves their position as the necessary bridge between two parts of their network, at a cost to both and a benefit that is difficult to state out loud, which is why it never is. Both parties eventually meet at a conference anyway, and mention it.
You need an introduction and realize the person you'd ask hasn't heard from you in two years. What would you do — send the ask with a warm preamble, or acknowledge the gap plainly and accept that this one costs you something?
A junior colleague asks for twenty minutes of your time and you're busy. What would you do — decline politely as the lowest-value request in your inbox, or take it, on the basis that the seniority ordering will not hold?
Two people in your network would clearly benefit from knowing each other, and being the bridge is useful to you. What would you do — keep the connection routed through you, or make the introduction?
