OK, bear with me just got back from the bar with the guys and slightly drunk. I just found you guys today, and your FAQ and read before posting is just mind blowing to say the least. Perhaps I should share a little about myself to give any advice givers a glimpse I to my psyche. TL;DR skip the next paragraph

My first girlfriend was freshman year of high school (very conservative high school) didn't go so far since my ambitions were adolescent dreams of being some kind of rock star. Lost her in the pursuit of my ambitions but she always kind of had some personal connection to me (she has a good boyfriend now and I'm happy for her). After that I spent high school hanging with a bunch of girls, admittantly to get in their pants but I was studying them the whole time, they saw me as a big brother, but now I look back on it I could have slept with any of them with the things I know now. Fast forward to college my first sexual encounter was this girl, who eventually became my girlfriend. We lived next door next year (I know big mistake) and she left me for my suite mate. I eventually hooked up with a former high school friend that second year, lost touch over the summer. Turned down sex from a girl since she was a raging alcoholic, emotionally unstable and clingy. My third year partied pretty hard (actually built a stripper pole for my dorm, but that's another story.) One party in particular was a night of complete wtf, a friend pulled me outside to tell me my neighbor was into me but she wasn't quite my standard and my bad experience with my ex the year prior turned me off. I ended up getting black out drunk waking up to the girl I was hoping to just ask out that night. Last thing either us remembered was sex (she actually did my dishes then left, making me a hook up legend amongst my friends). That morning I got an email from another girl at the party saying she thought I was cute and we should go out. My roommate had a thing for her so eventually after leading her on a bit I turned her down (is it an accomplishment if a girl tells you that you are the first guy to turn her down?) Next party I brought my hookup from my sophomore year, and my friend just whispers in my ear "you are fucked" and as I step out side my one night stand was there. She talked to my hookup, not saying a thing because she thought it was my girlfriend. Basically I chose easy sex that night and took my hookup. Two weeks later I found out my hook up had a boyfriend, two weeks later I find out that my one night stand came to talk to me because she was engaged (well not any more, I am a home wrecker.) My hook up told me her boy friend was shit and lived on the main land (I live in Hawaii) I spent the next 4 months trying to get her to leave him, eventually she told him and they broke up and we started going out. Lasted 4 months. Since then I've focused on my studies and only recently started back into the game.

I'm a regular at a e cig lounge and hit it off with one of the girls working there, went on a trip and she remembered when I got back. Exchanged numbers, invited her to a party which she didn't come because a ride didn't fall through. Meeting her this weekend at a rave. I know my chances are around 40% she comes back with me, which I know is more than ample but I just want r/seductions advice. I'm actually down for just a hook up to serious relation ship here, don't really care. The advice on being OK with making mistakes and getting rejected kind of sunk in, but I'm hoping to end my dry spell. I kind of am in shape, own a car, have a part time job as I finish me mechanical engineering degree, in my attempt to be "Mr.dreamy" in high school I can play guitar, skate board (considered getting sponsored at some point but decided against it), I bartend, can glove and dance amongst a few other things. Of I can get myself alone in a room with a girl I can end up inside her almost 100% of the time its just getting her to trust me to come back with me is my main stumbling block.

Sorry if I rambled on, still a bit drunk and unsure if I covered all the main points. You guys seem to have all the answers, so what could I do to test these waters?
