Instead of going to a random place like a bar or similar and hoping to meet future friends, you’re better off going to a targeted event where you will meet people with similar interests. A parents group thing, a house of worship event, game/theme night at a venue, etc. Whatever interests/hobbies you like.

Probably the best place to start though is your neighborhood. Invite people over for drinks, game night, pit fires, or whatever wit who you think you would connect with.

Can also try to develop friendships with co workers as well but that can often take longer.
