We understand. Building a network certainly takes effort, but we don't agree that you must be an extrovert to do it. Why? Because you already have a preexisting reason—your mutual dependence—to approach all who will be in the networks you build. Everyone in them is already connected to you and you to them through your present or future work. You depend on them, and they on you. Create your relationships by identifying and building on those preexisting ties.
