Alright before we start this off I just want to say that I'm no Don Juan and I haven't gotten much success yet, but here's a tip that DID help my sets improve. The concept is simple, statements not questions. This is where a lot of newcomers mess up and I know I use to mess up on this too. Most guys in there newbie phase will try to open with girls asking questions, trying for rapport. "How's it going?" "How was your day?" "How was class?" "What's your name?" and most likely the girl'll get bored. Statements to me, are just more straighter to the point than questions.
Question: So is working 8 hours a week hard?
Statement: Working 8 hours a week must be hard for you guys.
Question: Do you guys like the music here?
Statement: They've got some pretty cool music playing up here.
Question: Are you picking out something for your boyfriend?
Statement: You looked like you were trying to pick out something for your boyfriend.
Question: Are you guys Freshman?
Statement: You guys must be Freshman because I didn't see you around here last year.
Question: Are you guys excited for the game?
Statement: I know you guys are excited for the game tonight.
And that's basically what making a statement is, it's not asking a question, but actually making a statement about the girl. As you can see with that last one, you can also assume things in statements.
