Lately things have been going extremely well for me in every area of my life besides women. I have this really hard time getting into a positive mood and being more talkative (cold approaching). I run out of shit to say in 15 seconds.

I'll give an example of something that happened an hour ago.

I was getting coffee on campus today and a really cute girl paid for my cup of coffee ahead of me in line. She showed a ton of IOI's and was super nervous talking to me. When I found out she bought it for me and went over said thank you and that I owe her one a bit more small talk don't remember. I felt like a dumbass for not getting her number or asking her out.

I get the basics of confidence (strong upright posture, head up, relaxed walk, eye contact) I'd honestly not trying to stroke my own ego here but I'd say I'm attractive (with no charisma). My problem is and has always been, I literally can't change my fucking mindset and its drives me insane.
