Start contacting local socialist orgs, PSL, DSA, CPUSA, etc., go to their meetings and start talking to people. Look for groups that offer education, seem to have good internal democratic processes, good comradely vibes, and who are actively engaging in campaigns to struggle against injustice, and doing stuff that you want to participate in.

Groups that have lots of political discussion, rather than being obsessed with internal processes, groups that don't work with cops, and don't just follow the dems on everything, is another thing to look for.

Your local conditions are the most important thing to consider. I wish I could tell you what group to join, but it varies quite a lot. A small and very active group is probably better than a large group with mostly inactive members. I'm in DSA, because I want to build a alternative workers political party, and I like DSA, but I also know that not every chapter is the same, there's def some chapters I would not recommend, although my local is very good.

Once you find your political home, you can branch out, keep working with other groups help build coalitions in your city. The most important thing is, you can't affect change by yourself. We need to combine our efforts to be effective. Always speak up, speak your mind and rep your personal perspective, and groups that don't handle good well considered perspectives can be toxic. Then again, we can bring toxic perspectives with us, so always be open to hearing criticism and always be trying to improve yourself. Be patient and assume good intent but find a group you can work well with. Develop your cadres.

Virtually every group needs people who can take good notes and/or can begin meetings on time. Like that bar is so incredibly low, but the people who do it for their own groups are some of the only people who will do that reliably, and they're also often people who are the most committed and experienced. Taking those simple functions off peoples workload or even providing support in those areas can be invaluable to the whole group. Other things, like doing phone/text banking or tabling for like a few hours per month is incredibly valuable work, that helps with turn out to events and allows recruiters to make and build contacts. Very low bar, very high impact. One of the groups I'm involved with actually pays people to make calls so volunteering for that work on your spare time, and being reliable and consistent is another invaluable quality in a new member.

One final tip, it is better to do one thing consistently then it is to try and take on everything that you see needs done. Make room in your life for organizing, and don't take on extra unless you're sure you have time/energy for it. Tell people in your life like "I have a commitment every Thursday from 7-9 pm" and then stick to that for a while. Burn out will fucking destroy you. So check in with your self, and check in with others.
