Alot of people is following it like step by step by the book.
DO NOT DO THAT.
Just start to talk with her, and a good start is a compliment. F. example: "love the hairdo" or smth like that. And then she obviously saying: "thanks" Then u can start the with smth like; "We haven't talked so much, but I really want to know you more, if you want ofc." And she can't say no to that. Then she'll agree ofc, then u can meet.
But try to be body active with her, like when ur' with her in a "crowd" then tell a few jokes, get her to laugh and hold around her (IF SHE WANTS) If u see anything that replies to that she don't want ur arms around her, then let go and try again a couple days later, since u can't be to clingy.
Everything is the contact u get when u start talking, so try to do a good first impression. Im not saying that u have to, just try to be as usual as u are. And do not stress when talking, just take it chill. If u stress to much she'll notice and maybe she'll think ur some kind of weirdo or smth.
Good luck talking with her.
Hope my advices can help you to get ur girl
