You’ve settled into a groove on campus—you’ve worked out all possible latte stops between classes, which rooms are too cold and require a hoodie and which nights are best for going out. But before you get too comfortable, take stock of your campus Rolodex—think you know who’s who? This year, don’t limit your networking to fellow dorm mates. Whether you’re a first-year or a senior, take time now to befriend the people on campus who can make life easier, guaranteed.

Registrar.
If the registrar makes a mistake with your schedule or billing—or you do—be nice when you ask for help. Long before any problems arise, stop and chat when you have five minutes. In the future when you ask them to pull strings to help you get into that seniors-only photography class, they’ll know you as that “nice girl.”

Cafeteria worker.
When you arrive late for Mexican night and the guacamole supply is gone, cafeteria workers may share the whereabouts of leftovers. They also know the week’s dining schedule and where to score treats left over from faculty meetings. “Plus,” says Jenna, a sophomore at Boston University, with a smile, “they’ll be more likely to bring up the new carton of chocolate chip when the gallon in the freezer has been tapped.” Everyone needs an ice cream hook-up.
