Hmm, what is your mentality when you go out?
Is your mentality something like "This kinda sucks that I am going out alone right now. Why did I have to change schools man? This fucking sucks. The girls might think I'm a socially retarded loner. Fuck. I hope there's a cool group that I can appear to be a part of..."
Or is it more along the lines of "I am a motherfucking beast. I am Altair. I have accomplished this and that because I am a motherfucking beast. Let's see if there's a girl tonight who will respond well to my beastness. If not, fuck it. I'll focus on making friends then, and I'll try again another day. I am the most badass group here, a group of one. All these mofos wanna join MY group because I am a motherfucking beast."
If your mindset is similar to the latter, then I honestly believe that you're simply in a bad "dip" in your social life right now. I was a virgin until I was 19.5, and I am a transfer student who started his junior year of university at the age of 22 in 2012. I had my first sex with a girl outside of my social circle in 2013, 4 months after discovering GC. I had no close friends for a full year after transferring. I joined a frat, which has definitely helped, so you can try looking into that. I made my first group of close friends (they do not attend my university) in the fall of 2013. I was definitely in the second mindset. At like 3 in the morning, I went to the gas station alone like a motherfucking beast because I was hungry like a beast. I ran into these 4 guys there, who were also hungry, and I realized gas station snacks wouldn't suffice. We chatted for a bit, non-deep dive banter. Actually, I made fun of one of them because he had his button-up shirt buttoned all the way up. I told him he looked like a little kid. After bantering, I suggested eating at Denny's down the street because it's open 24 hours. They followed. We ate. I deep dived them at Denny's and found out the guy I made fun of and another guy in the group were rappers. They're just starting out, but they've actually produced 3 quite good singles so far. Even then, my mentality wasn't like "OMG these guys are awesome. What do I have to do to become a part of the crew?" Nope. I stayed a motherfucking beast. I kept being a deep diving conversationalist, discussed women (kinda showed value as a seducer), and invited them to my frat's parties. Since then, those guys and I have become real close friends. We made it a tradition to go to Denny's after my frat's parties, three of those guys and I frequently go day gaming together, and I help one of them with gaming--specifically texting. I met another dude just about 3 weeks ago. He was an incoming transfer to my university, and he posted on the school's transfers' Facebook group looking to make friends and for things to do because he just moved from out of state. I invited him out to go day gaming with the "Denny's group" and me, he actually turned out to be pretty good at it, and now he is part of the group and one of my closest friends.
My mentality was "I am a motherfucking beast. Let me get to know these guys. Let me take these guys under my wing--not as an asshole who thinks he's superior but as a true leader who builds them up. Let's see what I can learn from them. Let's see what I can offer, so that they may become motherfucking beasts like me." On a side note, I said "motherfucking beast" a lot in my reply which turned out to be a small autobiographical essay, and it may have come across as douchey, but I'm in no way douchey. I try to be like the "true gentleman" that Chase talked about in one of his articles. I just used "motherfucking beast" a lot because I felt like it.
If your mindset is similar to the first, then try to adopt more into the second example.
So anyway, stay optimistic, and be a motherfucking beast.
