Research has consistently shown that a significant portion of professional opportunities — new jobs, promotions, partnerships, clients, collaborations — never get publicly posted or advertised. They move through conversations. They travel through relationships. Someone mentions your name in a meeting. A colleague recommends you for a project. A contact at a company you have been watching reaches out because they thought of you. These things only happen when you have intentionally built a network of people who know you, trust you, and think of you when opportunity arises.
