Altair -
To give you some help I'll start by leveling with you: first and foremost, I'm 19 years old, have been in your shoes when starting to learn this over a year ago, and can give you some insight because I generally went after women who were in their early 20s, even my girlfriend now is 23.
A good number of them will ignore me and when I try to talk to them they will give me that weird creeped out look and some will actively be cunts
This indicates to me that it's you and not them so I strongly suggest working on your fundamentals first (walk, posture, eye contact, smile, tone of voice, etc) - and work on your approach as well (body language not facing her, smiling, locking eyes before approaching, etc). If you're approaching and they're consistently giving you creeped out looks then I can assure you that it's you and not them.
these days here in the US are very very tough to connect with and a lot of them aren't good people either. They are generally more cliquish, shallow, and rude than their younger counterparts.
I find this to be false or at the very least in equal portions - it's more of a barrier that hot girls have up to weed out the weaker men. More on this
here. It's your job to push past her shit testing and be attractive.
In actuality - some of the most optimistic and headstrong people I've met have been women in this age group: the ones who are driven to succeed and strive to be more than their peer counterparts (my girlfriend is like this, and several other girls I've messed with have been as well).
Another reality is that these girls are some of the most sexual because of their age - women peak in sexual drive around age 23-25 and it's much easier to sleep with women in their early twenties because of this - not to mention that college freshman come in with this idea of college being a giant party and will generally sleep with numerous guys her freshman year before becoming more serious about her schooling and getting into the swing of things.
As far as building a connection with these girls goes - I've got two pieces of advice:
-You don't need to build a strong connection with girls who are horny and you want to fuck.
-If you are looking to build a deep connection with a girl - it's because you're looking for a relationship - so it'll take you a little while to screen girls for qualities that aren't "cliquish, shallow, and rude" because these girls aren't usually looking for strong relationships.
All in all - work on your fundamentals first then work on your approach. Picking these girls up is definitely possible - it all amounts to how much effort you put into perfecting this craft.
