I recommend reading the original; the summary doesn't capture its style (and may not capture its substance, for all I know). This is interesting as a piece of rhetoric as well as advice.

At a glance, this is a book about productivity and time management. Any self-respecting productive manager of time would not waste an entire day reading such outdated and overly verbose prose.

TL;DR FTW

[EDIT]

I'm back, I just read the tl;dr version and I'm absolutely pumped! That really hit the spot. Going to listen to some of these film scores: http://songza.com/listen/action-movie-scores-songza/ and do what I thought would take a day in 4 hours.

This is an awesome tldr - Bennett's tone and verbosity where killing me, this way I at least have a clue as to what he was going on about....
