Of course it depends on what you want. If you want to be friends then just be yourself. If you want to date, dont think it as trying to pick her up and stay calm. But if you want to get laid, well there are many other things to do and not do. But thats not what I am talking about here. If you are trying to talk to a girl with the intent of getting together, you may fail cause you are nervous. So dont think of it like that. Just see where it goes.
