Essentialism requires the courage to stop—even when you’ve already invested time, money, or pride. The chapter targets the sunk cost trap: continuing because quitting would admit that earlier choices were wrong.
Uncommitting is framed as a strategic release. If a project, role, or relationship no longer fits the essential intent, the essentialist asks what it will cost to keep paying for it. The future cost matters more than the past investment.
This is emotionally hard because humans want consistency. But the book argues that refusing to cut losses is not loyalty; it is fear disguised as principle. Clarity without uncommitment is just awareness of your own drift.
The chapter’s promise is relief with direction: by cutting the wrong commitments, you recover energy for the ones that deserve you—and you stop mistaking endurance for progress.
