How do i break out of my shell?

Confidence is key my friend. If you hear someone talking about something you like jump in. For example Girl A: Did you happen to catch the Pretty LIttle Liars episode last night? Girl B No but I wonder what happened, its getting pretty intense. Then you jump in I saw it and it was very suspenseful, I can tell you the jist of it. Then if they say yes tell them or if they say no then say Well watch it when you get home because it is very good. :) And just be yourself kiddo be around people who like you for who you are then around people who like you for being fake.
