Why not simply honor your parents, love your children, help your brothers and sisters, be faithful to your friends, care for your mate with devotion, complete your work cooperatively and joyfully, assume responsibility for problems, practice virtue without first demanding it of others, understand the highest truths yet retain an ordinary manner?
