Another thing, and I know this is harsh, is do not appear desperate for approval or people who have not so honorable intentions will take advantage of you and mess with your head. Screw what people think of you and learn to love yourself before worrying about making tons of friends. As for me, I have a few very close friends who I trust, not a buncha "lukewarm" buddies like I used to have when I was a teenager and in my early 20s that I did all kinds of dumb crap with. Just chill, be yourself, be confident & compassionate and friendships will likely follow.
