I am coming from a slightly different background (Non-US/Europe) and am basically a bit about when to escalate things.I was pretty good and picking chicks up in the home country, I don't really have any confidence issues or anything, but somehow things work differently in the U.S. Also since I am slightly older than most college kids( I still go to college despite my age) the whole approach thing may work differently for me.Any basic yardsticks or literature I could look into ? Things that work in college please,I am not a night clun kind of guy.
