Building the Commune but apparently it’s only available on Amazon 😞
My advice would be to drop the "activism" part. We have enough people in DSA who act without thinking. We also have plenty of people in DSA who think without acting.
Your first step is to arm yourself with knowledge. You have to deprogram yourself from Liberalism which has controlled the way you think about the world and integrate information about the world to a degree which you don't now appreciate. The Left is weak and powerless now because the last time we were in a fight with the ruling class, they developed a number of intellectual landmines that you're unlikely even to recognize. You're full of zeal, you probably think One Person Can Make A Difference because that's the kind of story you've been reared on since birth. That's one of those intellectual landmines. There are more.
I would suggest starting with a book like https://www.amazon.com/Marxs-Kapital-Beginners-David-Smith/dp/039471265X. I'd be interested to see how much of your reaction is "No, that can't possibly be true or actually have happened, that must be made up".
Was gonna say the same thing so I'll just link it https://www.amazon.com/dp/0393322289/ref=cm_sw_r_cp_apa_glt_fabc_WTHESHY4M89CRY7J97CE?_encoding=UTF8&psc=1
I haven't read it, it is hella long. One day, though.
In the UK (not sure about US) we have this app called Too Good To Go where you can buy the food that otherwise gets thrown out. I've had some amazing meals at a fraction of the price they would have normally cost me.
