Boundaries create freedom by reducing the number of battles you must fight. Without limits, requests expand to fill your attention. With limits, others learn what to expect, and you regain time for what you chose on purpose.
This chapter treats limits as agreements with yourself: rules about availability, scope, and standards. They protect you from the slow creep of “just this once,” which turns into permanent access.
Limits also reduce resentment. When you say yes too often, you punish others later with irritability and underperformance. Clear boundaries prevent that by making capacity visible.
The paradox is that limits can improve relationships and work quality. People may not love your boundary in the moment, but they can trust it. The essentialist chooses reliable commitments over endless accommodation—and calls that respect.
