Many kids (especially high-achievers) see failure as a reflection of their worth. A failed test = they're stupid. A mistake in public = humiliation. This isn't drama—it's genuine fear.
Often this comes from how they've been praised. "You're so smart!" creates pressure to always be smart. One mistake threatens the identity.
Your job is reframing: mistakes aren't shame-worthy, they're information. They show where to focus next.
