OK.
So, my first question is, how often should I approach women? Is once or twice a day enough?

What is a good way to start a conversation with a girl? What is the first thing I should say?
What do I say and how do I say it to a girl to make her want me? Is it OK if I try to use humor? Is it OK if I use compliments?

My problem is, I run out of things to say. How do I fix that?

How long should a conversation between a girl and me last to get her interested? When do I ask for a phone number?

Are there any exercises that I can do at home, maybe in front of a mirror to help me?

What are good places to approach girls? Is the tube OK?

Did any of you guys ever experience hostility? I was in a bar one night, I approached one girl and got rejected, which I dont mind, I think it happens to everybody, but then the bartender came up to me and said "Don't hit on girls, you can't do that."
