I found this book more valuable than nearly all other productivity/business books I've read.

You'll really want to practice active reading/listening while taking this book in though.

This book meanders through many different ideas/studies/analogies. I would have forgotten most of the insights I had while reading this book had I not been taking notes.

As I continue to improve my work habits, I plan to reflect on the mountain of notes I took while listening to this audiobook.
