Introduction

• Deep Work: Professional activities performed in a state of distraction-free concentration that push your cognitive capabilities to their limit. These efforts create new value, improve your skill, and are hard to replicate.
• A deep life is a good life.

Part 1: The Idea | Chapter 1: Deep Work Is Valuable

• Once the talent market is made universally accessible, those at the peak of the market thrive while the rest suffer.
• The ability to quickly master hard things. The ability to produce at an elite level, in terms of both quality and speed.
• If you don’t produce, you won’t thrive—no matter how skilled or talented you are.
• The Intellectual Life. Sertillanges wrote the book as a guide to “the development and deepening of the mind.”
• Deliberate practice.
• Differences between expert performers and normal adults reflect a life-long period of deliberate effort to improve performance in a specific domain.

Chapter 2: Deep Work Is Rare

• David Allen’s Getting Things Done task-management methodology, which is a well-respected system for intelligently managing competing workplace obligations.

Chapter 3: Deep Work Is Meaningful

• A deep life is not just economically lucrative, but also a life well lived.
• If we give rapt attention to important things, and therefore also ignore shallow negative things, we’ll experience our working life as more important and positive.
• You don’t need a rarified job; you need instead a rarified approach to your work.

Part 2: The Rules | Rule #1: Work Deeply

• The key to developing a deep work habit is to move beyond good intentions and add routines and rituals to your working life designed to minimize the amount of your limited willpower necessary to transition into and maintain a state of unbroken concentration.
• Christensen wrote for a book titled The 4 Disciplines of Execution, which built on extensive consulting case studies to describe four “disciplines” (abbreviated, 4DX) for helping companies successfully implement high-level strategies.
• For an individual focused on deep work, the implication is that you should identify a small number of ambitious outcomes to pursue with your deep work hours.
• Zeigarnik effect.
• When you work, work hard. When you’re done, be done.

Rule #3: Quit Social Media

• The Craftsman Approach to Tool Selection: Identify the core factors that determine success and happiness in your professional and personal life. Adopt a tool only if its positive impacts on these factors substantially outweigh its negative impacts.
• And because your time returns substantially more rewards when invested in high-impact activities than when invested in low-impact activities.

Rule #4: Drain the Shallows

• Ruthlessly identify the shallowness in your current schedule, then cull it down to minimum levels—leaving more time for the deep efforts that ultimately matter most.
• Because, of course, in the end, a business’s goal is to generate value, not to make sure its employees’ lives are as easy as possible.
• Minimizes the effort needed from the receiver to respond.

Conclusion

• The ability to concentrate is a skill that gets valuable things done.
