More examples:

- taking (and maybe eventually teaching!) skill based trainings. Legal observer training. Street medic training. Protest martial training. De escalation training. Digital security training.

- learn how to make protest art. Banners, costumes.

- look around at the places you're most connected to. Church, work, hobby. Start talking to the people there, ask "what are we going to do about this"

But most importantly... find your people. Find community.
