Between that and a lifetime of low wage labor, by the time I started reading volume one I practically skimmed over the first 5 chapters because it all just seemed perfectly obvious when I went through it. If anyone else is trying to read capital but gets bored reading a bunch of simple algebra forms about bolts of linen and wage labor in the abstract because you already have a passing familiarity with Marxist concepts, I usually recommend people skim if not just skip ahead to Chapter 5 cuz that's where he really starts cooking once his whole economic proof is out of the way.
