📕 BOOK OF THE WEEK

This book explores the working culture and principles at Netflix and because of this unique culture, Netflix has turned into one of the most innovative companies in this decade. Interestingly, you can draw a direct line between Netflix's work culture and its actual product. For example, Hastings's demand for constant feedback is similar to Netflix's obsession with data collection. Another example is that Netflix employees manage their own time – like Netflix lets users manage their viewing experience.
I found myself saying, “Just one more page,” over the last few days as I plowed through the book.
