Why is it so hard to set boundaries? We’re afraid we might lose our job, push away someone we love, or embarrass ourselves in front of our friends. And when we finally speak up, guilt and anxiety follow us like a shadow.

But the truth is simple: boundaries in relationships are as essential as traffic rules—without them, everything spirals out of control. In "How to Tell Them to Go F* Themselves Politely," psychologist and neuroscientist Alba Cardalda teaches you how to say “no” with confidence and empathy. Recognize when you’re being pressured, manage feelings of guilt, and set boundaries without apologizing.

Because every time you say “yes” when you want to say “no,” you lose a little bit of yourself. And every “no” you dare to say brings you closer to who you truly are. A practical and direct guide to the art of saying “no.”
