Why ‘No’ Is a Full Sentence: Boundaries for Burnout Prevention

In today’s fast-paced world, the importance of setting boundaries has never been more urgent. As conversations about burnout and mental health take center stage, many are realizing that the inability to say ‘no’ is a root cause of chronic stress.
When we constantly say ‘yes’—to work, to family, to social obligations—we risk sacrificing our own well-being and productivity.
Learning to say ‘no’ is more than self-preservation; it’s a vital skill for thriving, not just surviving, in a demanding environment.
