Yea... you are already screwing sh!t up. Never go into anything with ANY expectations. Date because you want to have fun... to do this you have to pick things YOU want to do. You already think you have something to fvck up. You have NOTHING.... ask her out, and if she shows up you know you have a chance. You should not even be giving this chick any thought WHATSOEVER until she meets you on a date.
Having said that seduction is a three step process.
(1) Have fun. be a fun guy. Get her to laugh and and make her comfortable to be with you.
(2) Build rapport, get her to talk about herself. See if you can find out if there is some kind of connection. Also important is that you should not lie... if after spending an evening with a chick, you find NOTHING to connect on.... well, go find another chick, nothing is going to work with this one.
(3) If you are getting positive BL signs, then switch into seduction mode. I usually wait til the chick starts touching me, then I know it's game on. Others will tell you to start touching first... Yea it works, but you have to work harder, and I'm lazy and I'm not desperate to make sh!t happen. Start slow then go a little farther, until she pulls away or backs away... then you do the same, back up and talk some more, she's not comfortable with you so you have to build more rapport. Again, if you can not connect emotionally, just take her home and find another chick.
ALWAYS remember... you can not make something happen with ANY chick you want. You have to have something to work with, she has to like you and she has to have the ability to emotionally connect with you. If neither of these things are present then you are wasting your time.
