For reference, I've been interested in cold approach for the past year.

If I approach as I am now I guess I've got an opener and a couple cold read statements. Also, appropriate eye contact, smiling and personal space. But apart from that, I doubt I can maintain a conversation.

I certainly don't know how to build interest let alone attraction.

But my instincts are telling me if I wait until I've read a lot and watched a lot of infields I'll be missing out on something.

I guess what I'm really asking is whether I should actually approach now with nothing or wait for some far off day when I feel I've got the entire structure.
