This episode talks about the book "deep work," professional activities performed in a state of distraction-free concentration that push cognitive capabilities to their limit. It argues that this skill is becoming increasingly rare but also increasingly valuable in the modern information economy. Cultivating deep work is presented as crucial for quickly mastering hard things, producing at an elite level, and finding greater meaning and satisfaction in your professional life. The book then provides rules and strategies to integrate deep work into one's daily life.
