This is the right idea!

In my opinion the best thing, if it is an option for you, is to join a local left organization and develop yourself and the organization in terms of your theoretical understanding and practical efficacy, which basically to say reading and gaining expertise at taking action. And to be clear, when I say left, I mean something socialist.

It can be difficult to recommend a specific org because I don't know where you live and you shouldn't tell me. But I can suggest some things to do to help guide you:

• Pick a socialist one.
• Pick it by attending an action that they organize and getting a sense for the people and their positions.
• You can discover events by looking for posters in hotbed areas (college campuses, downtown) and social media.
• A good rule of thumb is that if they are anti-imperialist and name the US as imperialism's exemplification, their other positions will be better as well.
• Avoid Trotskyists and anything associated with Avakian.
• Once in an org, focus on building positive relationships with people, being dependable and active, and reading and then teaching once you feel confident enough.

If you use these tips you should end up in a good enough org and can help build it. It's okay if you end up leaving your first org. They are often just a way to get a sense for what exists locally and where energy and good practice are centered.
