My most useful insight/takeaway from the book was about leverage and what activities you choose to do as you progress in your career: in six months you could ship 1x engineers worth of output (or maybe 2x or 3x if you are really great) -- or you could help hire and onboard 10 engineers and create 10x worth of output. Thinking more strategically about the most effective way to spend my own time and energy was easily worth the nominal cost of the book.
