I agree that self flagellation mind set is bad, but sadly I do often fall into the trap myself.

I've thought about this, I'm on track to potentially make decent money (if I don't succumb to laziness depression that is). I think the top things one can do is promote unionizing and leftist politics at the workplace, at whatever capacity possible without losing your job. If that's not an option, I think the idea of being a socialist sugardaddy is good too, to mutual aid projects and political projects, while also staying as updated as possible in whatever socialist organization matches your tendency.
