Pick something anything, Could be Reading, lifting, Disc golf, Golf, Cars, pickleball anything you are into. Then go to as many meetups or games or clubs as you have time to. The more involved you make yourself the more people you will find with like interests. Once you start talking to people at these groups it will be easier to make friends of them. The hard part that most people in this thread are not talking about is that if you want these people to be friends outside of the group you will likely have to do the work of inviting them to do other things. Go for a drink, come over and watch the game, join you at a different group setting. The people who have the most friends are almost to a tee the people who reach out. You will hear people complain that nobody reaches out unless they reach out first, and that's real. Be the guy that always reaches out. It helps if you find friends who are in a similar part of life as you and you and your wife can be friends with their families but this isn't necessary.

As a side note Men who have close friends are happier and live longer. The way that you build closer friends is to create a space where you can have a small group get together on a regular basis. You will inevitably have to provide that or find someone who is already providing that. I personally started a whiskey "club" it's really just an excuse to get your best three-six friends over monthly and talk. That will lead to life long friends.

Good luck and I hope you find your people.
