The real power here lies in reversing our usual logic: we don't practice kindness because people deserve it, but because their struggles are invisible to us. When you snap at a colleague or dismiss someone's concern, you're almost certainly wrong about their capacity to absorb it—that person might be managing grief, a health scare, or simple exhaustion you'll never know about. Kindness becomes less a moral choice and more an act of intellectual humility, an admission that our judgment of others' circumstances is fundamentally limited. It transforms the habit from something noble into something pragmatic: treat everyone gently because you genuinely cannot know the weight they're carrying.
