Breaking the ice is the hardest part. Saying a simple "hello" will get the ball rolling. From there, work your way up into more meaningful conversations and all will be well. When people say you need confidence, they mean you need to say something to her. No one ever gets anywhere by not talking. Try to make her laugh or smile. Women remember small things and try to get her name (no longer emo-girl) and use it when appropriate and as much as possible. People LOVE to hear their name and she will be impressed knowing you remembered. This may seem hard, but it's really easy. Just say something so she knows you're acknowleding her presence.
