people are saying organizing, but realize it doesn't have to the start of the revolution or anything to be "organizing." just getting people to talk to each other, or just meeting friends/neighbors/co-workers yourself counts as organizing. I've had great success "hosting" a happy hour at my work. I asked a few coworkers if they wanted to grab a beer after work and then pitched them on starting a weekly happy hour. I've basically cold called a bunch of people at work with "hey, you seem cool. there are a few of us that get together for drinks after work. no big deal, but if you ever wanna join, come on out"

and then just show up every week. i've made some good friends, people around me have made friends, and now my coworkers know each other slightly better as people.
