Whats the easiest and simplest way to become attractive to girls?
Personally, I like confident but not cocky, humor without too much sarcasm, and try saying things a little flirtatious with lots of girls and not just the ones you want to ask out. Once a girl sees you making the day of some middle aged waitress or bank teller they will think they are getting a charmer who can make anyone feel better about themselves and that you are worth spending more time getting to know.
