I started reading this book on 2021/04/17. It's safe to say that it revolves around the concept of Decision-making in the brain, as discussed by Daniel Kahneman in "Fast and Slow". The book introduces the idea of System 1 and System 2 in the brain. The reason for discussing this topic is because Self-study itself is a battle against laziness. The book suggests that by making the lazy system (Habit) itself Metacognition, one can develop habits. This may also relate to books on Optimizing the brain.
