To be honest, I don't get impressed when a guy tries too hard to impress me. At some point, it even gets annoying. Maybe don't try to impress anyone. If a girl is going to fall for you, she will. Imagine all the effort in trying to impress her and then knowing you can't stop because the charm may wear off? I've heard of that happening. Just have a good long conversation and see where it takes you. It may save you from a lot of unneeded stress.
