Belief isn't naive optimism, it's a specific, visible bet you make on a person before the evidence fully supports it.

When you hand someone a stretch task and say, out loud, "I think you can do this," you're not just being nice. You're giving them permission to try something they'd otherwise have talked themselves out of. Confidence you show in someone becomes confidence they borrow until they can carry it themselves.

The risk is believing loudly and then withdrawing support at the first stumble. Real belief survives the first failure, that's what separates it from empty cheerleading.
