Apply reverse sunk-cost thinking to existing commitments
Ask "Would I commit to this today, knowing what I know now?" for every ongoing obligation.
Why it works
Sunk-cost bias causes people to continue bad investments because of what has already been spent (time, money, identity). Essentialism applies the correction not just to new decisions but to the standing pile of commitments already on the calendar. The reversal question — "if I weren’t already in this, would I choose it?" — breaks the prior-investment frame and evaluates each commitment on its current and future value only.
How to do it
- List your current standing commitments (committees, projects, social obligations).
- For each, ask: "If someone proposed this to me today, with no history, would I accept?"
- If the answer is no, plan an exit — even a slow one is better than indefinite continuation.
Evidence
Sunk-cost effects are among the most reliably replicated findings in behavioral economics. The counterfactual question ("would I choose this fresh?") is a standard debiasing technique in decision-quality frameworks. (observational)

Common mistake
Reviewing only big commitments and ignoring the small recurring ones — the small ones are often the largest aggregate drain on time.

More practices for Essentialism: The Art of Eliminating the Non-Essential
- Apply the extreme criteria filter ("If not hell yes, then no")
Raise your acceptance threshold so high that only clearly excellent opportunities pass.
- Say no clearly and without over-explaining
Decline requests with a brief, honest reason — not a cascade of apologies and caveats.
- Identify the single most important output for today
Choose one task that, if completed, would make the day a success regardless of everything else.
- Reserve unscheduled time to discern what matters
Block undirected time for reading, thinking, and exploring — without an output requirement.
- Ruthlessly edit projects in progress
Cut content, scope, or steps from anything in progress that doesn’t serve the core goal.
- Exit obligations gracefully and early
When you realize a commitment was a mistake, exit cleanly before deeper entrenchment — not later.
