Read theory, it's literally online for free. Join a reading group. You spend hours doom scrolling on Twitter to no end. All that's gotten you is deep knowledge of every twitter beef between 400 follower nazbols.
Edit: It’s not an issue with the site but online discourse about the left in general. Why are y'all upset about shoeonhead or black hammer or whatever new group of dumbasses is saying some new dumb shit. I'm talking about how every few days lots of leftists are surprised and upset that their fav twitter personality said something really stupid.
Most of Lenin's texts are basically angry effortposts which are usually addressing something very specific but from which you can draw much more general conclusions and see how he applied marxism in practice. However there is also Imperialism: The Highest Stage of Capitalism which is a little bit harder but it's more general. However of course it's worth reading the shorter texts by Marx and Engels before all that. Just don't try to read Capital because you'll burn out.
Imperialism: the highest stage of cringe will be my endpoint for reading Lenin, then I'll move on to short Marx and Engels. Thanks for your advice, but I'm going to use the reading tactics that usually work for me. I might revisit this if I find my strategy not working.
Yeah alright but I'm saying that partly because there's a logical progression in that Lenin builds on Marx and Engels and occasionally even departs from them so it's worth knowing what they said first.
