I know this is kind of a basic question but I'll get more specific. I'm a busy guy, I work full time, I have a dog, a property to maintain, dedicated hobbies being indoor bouldering (2x a week) and golf (2 to 3x a week) that I do for both fun and goals of self improvement. I self diagnose as having a little adhd and being introverted.
I just find it so hard to go out and be social for the sake of being social, as it's usually involves doing something that I don't enjoy doing. I can't fake having a good time when I'm not, I second guess myself, I wish I were at home or doing something else. I have made a couple friends through my hobbies but it never goes outside the hobbies. I see other friends going out to bars or random events and having a much more fruitful social life. I am social when I'm out walking my dog or at work but it's always just passing niceties, nothing deep develops
