What do we mean by your good self? Good question. Ask yourself that question, and be generous and kind while answering.
Peer into your heart and soul with the brilliant vision of your imagination, and find an image of yourself that you love. Think of all of your best qualities, your most positive aspects, and your talents and abilities. Then, mentally rehearse scenarios where you picture and imagine yourself asserting all of that goodness into the world, offering it gently and enthusiastically to anyone who is open to receive.
