To leave the distracted masses to join the focused few, I’m arguing, is a transformative experience. The deep life, of course, is not for everybody. It requires hard work and drastic changes to your habits. For many, there’s a comfort in the artificial busyness of rapid e-mail messaging and social media posturing, while the deep life demands that you leave much of that behind. There’s also an uneasiness that surrounds any effort to produce the best things you’re capable of producing, as this forces you to confront the possibility that your best is not (yet) that good.

The “great and profound mistake which my typical man makes in regard to his day,” he elaborates, is that even though he doesn’t particularly enjoy his work (seeing it as something to “get through”), “he persists in looking upon those hours from ten to six as ‘the day,’ to which the ten hours preceding them and the six hours following them are nothing but a prologue and epilogue.

The key lesson I want to extract from Marshall’s story is that management is about more than responsiveness. Indeed, as detailed earlier in this chapter, a dedication to responsiveness will likely degrade your ability to make smart decisions and plan for future challenges
