1. Venues. There are girls everywhere.
2. State. It's not a state driven activity. You need to have a generally positive outlook and know that however you feel you will take positive action.
3. Approach Technique. Walk towards the girl you want to talk to.
4. Topics. Say anything. Nothing is out of bounds.
5. Stupid theories. I'll leave them to you Dolphin
Let's not complicate things. The fact is we all just need to bite the bullet and get on with it. Anything more is superfluous and simply a method of trying to minimise rejection.
Don't structure your game around not getting blown out. Structure your game around getting blown off.
Peace,
