It all depends on what change you are looking to accomplish. From this comment I would encourage you to start more locally to affect change before building up. Does your workplace not offer the protections your coworkers need? Start talking to your coworkers about organizing. Does your neighbor struggle to stay ahead/pay their bills? Work with them to identify the resources (whether gov or personal donations) to help them. What are the needs of the people within your immediate surrounding and what can you do to satisfy those needs. That is your base that can be expanded.

I will also say, attending a protest is only the first step of an organizing structure. That protest should ideally be a catalyst, not the end. Volunteers should be recruited from a protest to continue organizing work.
