So, I'm going to read this next month. What am I in for? Is there any preliminary reading you'd recommend?

>Start reading capital a couple of weeks ago
>Pretty dense shit from the outset even Marx in the preface warns about how thick his explanations in the first part can be to someone who is not used to this kind of stuff.
>Get to Chapter Three: Money, Or the Circulation of Commodities
>Want to fucking hang myself
>Get through it barely understanding anything
>Arrive to Chapter Four: The General Formula for Capital
>Go through it and suddenly I have an epiphany and start to understand Chapter III completly
>C-M-C, M-C-M, M-C-M', where M' = M + D M formula for the Surplus Value
>Feel like my brain is about to nut

So is this the power of dialectics??

I'm halfway through pic related, are volumes 2 and 3 worth reading?
