Not really. you can't force anyone to be your friend, and if there is some supericial reason someone doesn't like you, you can't really change that (not without a big change I guess. I'm sure if you got ripped you'd suddenly have a lot more "friends). You're at the mercy of luck in where you meet and who clicks with you. And that gets harder as meetups and socialties become more based around how drunk you get or if you like sports. I like neither.
