Got out of a relationship about in May and since then I've been trying to readjust to the whole flirting game once again. It used to be really good in Freshman year; I had a lot of confidence, didn't give a shit about what I'd say, admired myself and could say just about anything to any girl. Rejection didn't phase me. Then after my relationship I got into this phase where I lost my mojo. I started caring more about social interactions and what people thought of me. I began letting my emotional side take a hold over my logical side, even preventing me sometimes from going up to girls and talking to them. How do I get back into my I-don't-give-a-shit state? What must I do to relive the badassery that I once held in the palm of my hand?

P.S. I've been going to parties, hooking up occasionally etc, but it's still not working out for me. Can't seem to approach an attractive girl randomly just like how I used to. Met this one girl and we were really hitting it off. Then we hooked up the second time we met and she sorta friendzoned me at that point? Then we hooked up a second time recently but she's still acting very detached?

I'm in college, I've read the Tao of Badass a couple years ago and some reddit posts on Models.
