1. Have an open-door policy.
When you're at home in your residence hall room, don't be afraid to leave your door open—it's a good way to strike up conversations with your neighbors.
2. Share a meal.
Everybody's got to eat, right? Instead of taking food to-go and eating in your room, ask your neighbors if they want to walk to the Beaver Dam with you.
3. Ask for homework help.
Take advantage of the fact that many of your neighbors are most likely first-year students just like you, and someone in your hall is most likely in the same classes you are.
4. Give it time.
If you feel lonely when you first start college, rest assured: that's normal.
