1. Be aggressive: Talk in class, join that club, walk up to that kid on your hall. Just like in dating, sometimes people aren't going to just befriend you because you exist. So make the first move.
  2. Join a study group with fellow classmates. You already have something in common.
  3. Get involved by joining sororities/fraternities, volunteering, joining clubs, getting a part-time on-campus job. There's always something happening on campus, step out of your comfort zone and give it a try.
  4. Live on campus. You'll have more opportunities to meet people and be more inclined to join clubs on your off-time.
