When you approach a girl, she is going to be attracted to you primarily based on your confidence, regardless of where your confidence comes from or if it is valid or not. Let me tell you guys a funny story that happened to me in field a few years ago before I got into studying seduction and pickup and would often mistake friendliness for flirtiness and vice versa. I was in college and attended a study session for one of my classes and got a girls number in it so she could give me notes from the study session. I texted her after and subtly tried to shoot my shoot with her, but she deflected my advances politely. Because I had a very hard time reading women, I misinterpreted it as her totally flirting with me and coming on to me very strongly. I immediately became very confident and assured of myself because I totally thought this girl was into me when she wasn't. My voice tonality and walk and demeanor completely changed almost instantly. A few minutes later, I approached another girl outside of my teachers office with complete confidence and swagger and got her number and followed up with her the next day and she was actually completely into me and very excited to hang out with me and had a very high level of initial attraction towards me, likely because of my high level of confidence that I displayed when I approached her. I was essentially able to use my falsely obtained confidence from a girl who wasn't flirting with me at all to actually successfully pick up another girl. So guys, remember, girls aren't going to wonder why you're so confident when you're approaching them! They are simply going to feel your confidence and be very receptive to you off of it! I highly doubt the girl I approached and successfully picked up was wondering why I was so confident and whether the confidence I was displaying was actually valid or not! So when in doubt, unless the girl is showing obvious signs of disinterest, always assume she is into you because it will lead to an increase in confidence which will lead to a better outcome almost always!
