First off, popularity is nothing but a cruel, sick joke. Be yourself. So what if you don't fit in? I've had bad experiences with "popular" people, and trust me, a lot of them... aren't good people to make your "role models" or whatever.
As for talking to people, just be confident!
Couldn't have said it better.
Why try to be perfect? It gets me no where.
I'll be a fantastic friend. Give me a chance.
If you want someone to talk to I'm the perfect person, I'm trust worthy and will actually listen and care
