Ok since I am in a good mood and kinda feel like you're not actually levelling us with your zero self-confidence post here's some simple advice:
1a) Don't be so results oriented
1b) Don't worry about the next step so much, it will present itself
1c) Don't put pussy on a pedestal
2) Talk to her about whatever (your body posture and tone of voice watter way more than what you say initially) and get her to talk about herself as soon as possible so you can figure out what she likes to talk about
3) If you are not interested in what she says or disagree with what she says you do not have to show interest in/agree with her. This is like the number 1 mistake guys make. When a guy says something retarded 99% of us guys would be like: "That's one of the dumbest things I heard today, are you drunk or something? LOZL" when a girl says the exact same a lot of guys will go: "Hehe *nervous laughter* yeaaaahh... so you go to class X too? [or any other common question she gets about a topic that's boring to everyone involved]"
