Are there any quick ways I can study, read and process socialist/communist theory?

No matter how many times I try to study theory (with Cowbee's method of taking each paragraph and boiling them down simply in their own words), I never get to fully process theory. What should I do?

This goes out to all the DBZer0, Lemmy.ml, Hexbear and Lemmygrad people out there reading this. Seriously!
