" Saying No is a way for you to communicate with yourself. It forces you to breathe, which breaks the freeze response. It gathers your energy. It gets your adrenaline going. It reminds you of the [self-defense] class, your muscle memory, the support of the line [your peers], and the fact that you have the right to fight for your own safety. "

― William Ury , The Power of a Positive No: How to Say No and Still Get to Yes
