I do not mean this as a rhetorical question: I mean it literally. Tell us what’s stopping you! I don’t want to invalidate you, but the opposite. I’m sure people here would love to help if it’s possible. Post away!
Personally, I think Covid and the general amount of work everyone does are the two biggest obstacles to community building. Not just for me, but everybody I know. It’s nearly impossible to build a community when nobody has the energy to even play a video game together, and actually meeting up in person can literally kill you. There are definitely solutions, but we need to realize them as problems first to find them. If you have suggestions, please share them! Same goes for the issues everyone else shares (if they’re ok with help, of course).
Try to form connections with the exploited and oppressed people in your locality via whatever means you can. Listen attentively to them and their problems whenever you get the opportunity, understand them and use the theory you know to analyse what you have heard and seen. Take the results of that analysis and try to apply them; even if it's just trying to agitate more effectively, keep thinking about how to adapt your line and practice to the circumstances you find yourself in. Always be on the lookout for other communists/anyone else who seems like they would be down to help organise the working class. If you find anyone like that, talk to them and work with them. Some of the folks in your local party branch may feel the same as you about the tactics being ineffective and would welcome some fresh ideas about how to organise.
Basically, do what a communist does. It takes practice and if you're new to it, it's gonna feel a little stilted at first, but this is how communists organise and lead.
