Don't be dry as fuck, that's my advice. You can be as attractive as can be, but if you have the personality of a door knob, that's a huge turn off. If you're not a very interesting person, find someone who's similar to your so you have something to talk about. IMO you can win most every girl over with just talking and being interesting. This has been my experience at least, although I wouldn't say i'm the ugliest guy out there(To be humble I don't think im all that attractive but from what i've heard, I am so I don't know what to believe). But yeah, just be interesting, don't have a conversation that's
