check out your local community, form alliances with others - there's often not much more to it than getting to know your neighbors and helping each other out whenever possible.

I just wanna point special attention to point 4. This may be the most important one. 5 is as well. The others are too but probably are easier than the first three.

Location based communities are often tough to form in densely populated areas. A good first step is to try to break the ice with people you've run into more than twice. Regardless of age/race/peceived personality (within reason).

Most people may get along with others more than I do. So I can struggle with this. Especially since the pandemic. I know I'm not alone in this regard with covid, crime and public unease. Be diplomatic with yourself and others, when conflicts may arise.
