Every once in a while, I meet a person who radiates joy. These are people who seem to glow with an inner light. They are kind, tranquil, delighted by small pleasures, and grateful for the large ones. These people are not perfect. They get exhausted and stressed. They make errors in judgment. But they live for others, and not for themselves. They've made unshakable commitments to family, a cause, a community, or a faith. They know why they were put on this earth and derive a deep satisfaction from doing what they have been called to do. Life isn't easy for these people. They've taken on the burdens of others. But they have a serenity about them, a settled resolve. They are interested in you, make you feel cherished and known, and take delight in your good.
