Discernment is the skill of separating signal from noise. The book pushes an uncomfortable ratio: most things that look important are not, and a small number of decisions create outsized consequences.
Without discernment, you treat every request as urgent and every opportunity as rare. With discernment, you look for the few variables that drive the outcome and ignore the rest, even when ignoring feels socially risky.
This chapter encourages a shift in evaluation: stop asking, “Is this a good thing?” and start asking, “Is this the right thing?” Good is abundant. Right is scarce.
Discernment is not cynicism. It is respect for your limited time—and for the fact that attention spent on trivia is attention stolen from contribution. Scarcity makes discernment non-negotiable.
