How to do it:

Do your organizing in person, or use Signal. Consider friends who seem to have similar resistance priorities: people who are upset about the same things, and have a similar take on news stories. If you’re already good friends, just ask if they want to form an action pod. If you don’t know them as well, start slow with a visit over coffee. Bring up politics. See how they respond.

Once you have one more more candidates, plan a simple, non-controversial resistance event with easy organizing requirements: a visit to your Senator’s office, or a sign making party, or tea and Postcards to Voters. If it goes well, up the ante with something that takes more organizing and investment: attend a protest or tackle a project as a group. You’ll get a feel for which people match your enthusiasm and values. Activism is like anything else: there are practical, personal, and ephemeral elements to a group that really works. Keep trying until you find 1-5 other people who mesh well.

4-6 is the optimum size for an informal group to maintain agility. If you find yourself growing beyond that size (or tackling projects that require more people) either let each core person head their own “team” that they take responsibility for managing and communicating with, OR study organizational principles and find mentors among the activist community to help you grow. Many big groups began with two people and an idea. The successful ones had experienced organizers, or effective mentors.
