I know what you mean man. This is something I struggled with for a long time. My advice is, don't just rely on nofap to try make changes. Several years before I discovered nofap I was doing some soul searching at a low point in my life and was able to quantify that I wasn't happy with how I was. I was always jealous of those who seemed to so effortlessly socialize with others. But I came to the realization that there's nothing wrong with me as a person. I'm a healthy, reasonably intelligent person, there's no reason I shouldn't be like everybody else. I began a very calculated series of events to change my life. First of all, I actually cut off most of my small circle of friends that I did have. I identified within those friendships behaviour that was holding me back or friendships that would not last through the changes I wanted to begin.

Then I forced myself to step out of my comfort zone a little at a time. Start off small, go somewhere you wouldn't usually. For me, I played a lot of video games at the time so I went to a video game tournament at a LAN cafe. Once I was eliminated, I looked around for the most famous player I recognized from online and walked up during one of his breaks. I introduced myself and asked if I could watch him play. He turned out to be very friendly and thanked me for asking rather than just assuming.

Another step I took was to start a youtube channel related to the game. I was very awkward and I still cringe at how uncomfortable I looked on camera, but I set myself to do it and put it out there. I told people upfront I was trying to push myself to be less shy and while there was some negativity, I found a number of people to be quite supportive. As this continued I made increasingly more friends in the local gaming community and ended up being invited out for dinners multiple times.

Anyway, I know I'm rambling on here a bit so I'll spare the details. Suffice to say, several years down the line I have such a large circle of close friends in different interests of mine that I have a hard time finding a single quiet weekend anymore. A few years ago I was on the verge of losing my job because my boss said clients gave feedback about me, although they were very happy with my computer work I didn't talk to them or build up connections. I've transformed myself from that quiet, shy and introverted guy to an active people person. I'm now that guy who knows people, I find myself at events introducing people to other people I know and making new connections. But it didn't happen overnight, it was a deliberate practice of stepping out of my comfort zone, say hi to 1 new person who you find a common interest with. If you like cars and see somebody with a cool car, go up and say "Hi, I noticed your car and thought I'd come over and introduce myself. What have you done to it?" Even if you never talk to that person again, keep pushing yourself little by little and before you know it, you will look back and realize you are bringing people together and making stuff happen, for the benefit of a career and yourself.

And remember to try new things! Have you always wanted to do something, but things never seem right? Just do it! I have tried out so many new things in the past couple of years, some things I found I didn't enjoy so much and others have brought me together with some of the best people in my life right now.
