New York Times columnist David Brooks offered a memorable take on the idea a few years ago: “In today’s loosely networked world, people with social courage have amazing value,” he wrote. “Everyone goes to conferences and meets people, but some people invite six people to lunch afterward and follow up with four carefully tended friend-ships forevermore. Then they spend their lives connecting people across networks. People with social courage are extroverted in is-suing invitations, but introverted in conversation—willing to listen 70% of the time.”
