Ok so I'm obviously new to the website and my main problem is a lack of motivation.
I usually am ok with talking to people in general minus occasional awkward quips. I've had sex with girls and sometimes approaching really isn't a problem for me if I'm with some of my buddies. My problem is that I always rationalize ways out of approaching girls alone. I know you're not supposed to think about it like the 3-second rule but I tell myself to go and I don't. That's the thing. I just sit there, there isn't really an impetus for me to jump in it. I want to but I don't. When I'm with friends or even girls I know I crack jokes and am pretty likeable but when I'm around people I don't, I guess I don't assume the same sense of humor but it comes off as me being boring. I don't really like that. I'm also pretty new to the whole PUA concept.
You need to stop being outcome dependent. Just talk to people.
