I am a 21 y/o university student in the US. I've gotten a lot braver recently and have been approaching about twice a week, basically any time a pretty girl IOI's me. So far my approaches have consisted of girls in class, girls at the club I frequent on weekends, and one cashier at the grocery store near my apartment. I've been rejected every time, and I'm not sure what I'm doing wrong because at least 50% of these girls were eyefucking the shit out of me. I'm a funny and confident guy on a good day, which is about 40% of the time. Nerves generally are not an issue. Can you guys tell me how you would handle approach following an IOI?
