If we are healthier when we are caring, empathetic, and open to others, it means we are born to be kind. If we push our way forward, cultivate hostile thoughts, or bear lifelong grudges, we will not be at our best. And if we ignore or repress our positive qualities, we may harm ourselves and others. As psychiatrist Alberto Alberti maintains, love that is not expressed becomes hate, joy that is not enjoyed become depression. Yes, we are designed to be kind.
