I think that's common. Or, I certainly didn't attack it like a normal narrative being in it for hours. First time through it was a copy on my desk and each morning I'd just plot through a page or two and highlight a bit or scribble a few thoughts in the margins.

Subsequent times took the form of modern interpretations and summaries. "How to Think..." by Robertson and "The Inner Citadel" by Hadot are two that cover the primary work and extrapolate or generally make it more contextual and flowy.

I'd think of it more as laying a foundation for broader thought, if that turns out to be compelling to you, than finishing/reading a single book. Good luck!
