Deep Work by Cal Newport is a book that describes the concept of “deep work”—professional activities performed in a state of distraction-free concentration that push your cognitive capabilities to their limit. It argues that this type of work produces new value, improves skills, and is hard to replicate, contrasting it with “shallow work” which is non-cognitively demanding and easily replicable. The book provides a framework for training your ability to concentrate deeply and structure your schedule to make more time for this valuable work, which is crucial for success in a distracted world.
