First post even though I've had an account for months. So basically I have ADHD and am autistic, on top of that I've always struggled with self discipline and motivation. All of this has been made worse by a traumatic event causing me severe depression that I can't seem to get out of. I genuinely want to read theory to become a better Marxist but I can barely manage a few pages at a time before giving up. Any ideas?
Audiobooks while doing menial tasks (like cleaning).
Capital (all volumes) is available online for free.
If that's still too much then I recommend Prof David Harvey's lectures on Capital Volume I (he has some on II/III as well, but I will suffice). They're also freely available on YouTube, etc.
I would actually recommend audiobook/reading and then listening to Harvey's lectures for further context. He's not perfect by any means, but he does offer a lot of insight and additional context due to his experience over a super long career teaching courses In physical universities. Remember to consider that he has biases, as we all do, and his commentary and vision are limited, as we all are.
Reading and studying Capital, at least the first volume, is absolutely critical imo to anyone who calls themself a Marxist. Of course other books are foundational as well, but that one book, if you study it and pay attention, will get you most of the way.
