Seriously though, I think people in the modern age have forgotten we're social beings and one of the nicest and simplest things that can happen is to have someone acknowledge your existence. Saying hi to the girl in the store a nice, tiny, little compliment and is likely to engender her more to you than otherwise. I think you want to avoid feeling that you have to make a big introduction of the sort "Hi, my name's Troy McLure and I think great and we should date" etc. Take it down a notch, just say hi and leave it at that, or maybe compliment her sweater and following it up with a question, see where it takes you...
Just my two cents
