Vigilance protects you from manipulation, but total isolation can become its own prison. The danger isn’t only naïveté—letting everyone in—but also closing the door to everyone. The real balance is discernment: know your weaknesses, don’t give trust cheaply, but don’t refuse it entirely either. Close the gates to the crowd — not to everyone. True strength is being able to say: “I am no longer naïve” without also saying “No one will ever enter my life again.”
