Give unconditional love. Let love from deep within in your heart flow into all directions. Start with your parents, spouse, children and friends.
Express gratitude. From the time you were born till today realize that you have received help and encouragement from people you know, to the books that you read, the money you received from work, and the inspiration that you got.
