I've been leading the effort for building up a local institution that has been in a "zombie" state of existence for a while.
It's a very small org, not necessarily communist, and even our political parties don't pay much attention to it. It's stressful and sometimes a thankless job. Since we're rebuilding it and have very few people, everything takes way more of my time than it should.
But it's damn satisfying to see how much can be done just by pooling together some working class people, and how much we help the lives of people affected by us, materially or socially. It's made it even more clear to me how mentally unsustainable society has become through individualism.
So this is your regular call to get organised.
You don't need to devote too much of your time to it, because every little bit helps a lot. You also don't need to build something from the ground up, you can join a bigger effort around you. It also doesn't need to be a party chapter (specially if you don't have one near you), it can be other necessary organisations like tenants'/trade/workers'/students' unions, animal rescue groups, homeless shelters, food banks and soup kitchens. Heck, even some churches can often have progressive projects that materially help the working class.
From a theorectical and material perspective, no revolution will come without organised and connected labour with practical experience. But from a personal and subjective view, building up those connections in service of your class and community is something you probably can do in your immediate surroundings and feel in concrete terms what Marxists mean by "organising" and how effective it can be. So it's a win-win scenario.
less motivational stuff
Eventually, without a party coordinating and leading the way, and under a capitalist regime, every organisation will reach their limits of what they can do alone. This is the moment where a proper party can combat opportunism and heighten class conflict.
But I assume most here are from countries where labour is so disorganised and disintegrated, to the point where those limits are so far away that they're invisible.
This post is not meant to dissuade from party work, but rather as a generalisation for eager comrades in situations where party work seems impossible. Eventually even soup kitchens and affordable TNR clinics will stumble into class conflict, which they can't win without a good Marxist party. But people won't even believe in a proletarian revolution as an alternative, and therefore won't agitate for one, without first hand experience with worker-led smaller projects such as those soup kitchens and affordable TNR clinics.
I could write some more on the nuances of local organising, but this was meant as a motivational post. For more theory, click every single link in the Black Panther MIA page.
