Smart Faster Better by Charles Duhigg
I was really excited by the title of this book, I was expecting it to tell me about some other methods to be productive and share with me some insights. In the end, it turned out to various case studies on varying different situations but it stopped so far as tell you the method that was used or summarizing the different approaches. I was disappointed with this book and cannot really recommend it. Maybe in the future, I would listen to it again to double confirm my thoughts.
