Unless, like me, you are positioned permanently in a public place, you’re probably going to have to go out to make friends, even ones you meet online. One popular strategy is to pick something you’re interested in that other people do, and go do that. Join a club, volunteer for a charity, go to events sponsored by BC or other groups on campus. Some humans find Meetups helpful, and there are Boston-area meetups on anything and everything. Be yourself. If all of that seems like too much, try saying hello to one new person a day. When that gets comfortable, try starting a conversation with them.
