When I moved out of my parents place, and I was running my own business, I had no peers at school anymore. I had no coworkers. All I had were customers and low-wage employees. Not my ideal social circle.
Here's what I did.
Dating apps: I was in damn good shape and lived on a lake. So I threw parties and invited all the chicks I could. I'd have 15-30 girls at my house every friday in July. I only had a few dudes to invite so I let some of the girls bring friends if they wanted as long as they brought plenty of drinks. I ended up meeting a group of army rangers who were some pretty cool dudes and we would party each week alternating between my place and partying back on base at their place. I met more and more people and I would always have some cool friends to go do stuff with on most days of the week.
On the days leading up to the parties, I would invite chicks over to hangout that I had invited for the party later in the week. So that was my dating life.
Offer something of value along with being a cool dude. The whole plan falls apart if you're not interesting or attractive. You need to be a man that people want to be around, but not only that, then you have to put yourself out there. You don't have people around you by default since you're new in a city. You have to manufacture it yourself and get in front of people. The way I did it was lake house parties. You don't have to do anything similar but it makes it easy.
Then, make friends on this forum. These people are amazing and I've met some great friends on here. Hell, I traveled with
@GravyBoat across India last year.
Finally, go out and DO STUFF. Get some hobbies. Go to a concert. Go to coffee shops. Go rock climbing. Do stuff you like to do and start introducing yourself. Have some energy and be interested in other people. Other people are usually just shy and need to be talked to first before opening up to someone. Be the guy who says hi first. Be the organizer. Be the guy with something going on. Be the introducer. Be the host. Be the guy who's always trying something new. Say yes to things more often.
That's how you'll meet lots of people. It may not always mean an increase in productivity for your business, but if you just need stuff to do and need a bit more social interaction in your life, it will definitely help a lot.
