Greg McKeown

Author of Essentialism, the book on disciplined pursuit of less. Kyle’s notes credit McKeown’s own working practice as the source of the book’s central disciplines: a “monk mode” writing regimen of eight-hour, no-interruption blocks, and the “90 Percent Rule” for filtering decisions. Kyle read the book in story-cataloging mode — most of his notes begin with “Story:” — treating it as a source of parables and worked examples for building a personal operating system.

In Kyle’s wiki the book sits alongside Deep Work on the focus-protection thread (McKeown’s monk-mode blocks and Jeff Weiner’s blank-calendar practice as the operating-system version of deep work), and connects to the Pareto Principle via the book’s “trivial many vs. vital few” framing.

Context: Greg McKeown is a writer and speaker on leadership and productivity; Essentialism: The Disciplined Pursuit of Less (2014) was a bestseller, followed by Effortless (2021).
