Greg McKeown's "Essentialism" is built on one simple idea: less but better.
It is not about getting more done in less time but getting only the right things done. For CEOs drowning in options, opportunities, and other people's priorities, it is one of the most clarifying books you can read, and its core warning sticks with you: "If you don't prioritize your life, someone else will."
Deciding what matters most before it is too late is exactly what an exercise like Five Wishes forces.
The Four Moves
McKeown organizes the discipline into four stages. Essence is the mindset shift: from "I have to" to "I choose to," from "it's all important" to "only a few things matter," and from "how do I fit it all in?" to "what are the trade-offs?" Explore is about discerning the vital few from the trivial many.
This means protecting time to think, to rest, and even to play, then selecting only with extreme criteria.
Eliminate is the hard part: cutting the nonessential, learning to say no gracefully, and uncommitting from sunk costs. Execute is making the essential almost effortless through buffers, routines, and a relentless focus on "What's Important Now?"
The 90 Percent Rule
The single most practical tool in the book: when you evaluate an option, score it against your most important criterion from 0 to 100. If it scores below 90, treat it as a zero and decline.
As McKeown puts it, if it isn't a clear yes, it's a clear no. That one rule, applied honestly, eliminates most of the "pretty good" commitments that quietly crowd out the great ones.
It is the same discipline behind making high-stakes calls under uncertainty: Thinking in Bets.

"Less but better" is the personal-productivity twin of everything we believe about scaling a company: find the few things that actually move the needle, and ruthlessly offload or eliminate the rest.
It pairs naturally with our ABC Model exercise and the whole idea of delegating to a fractional executive so you can spend your time where it counts.
