"I am one of those who believe that spiritual progress is a rule of human life, but the approach to perfection is slow and painful. If a woman elevates herself in one respect and is retarded in another, it is because the rough trail that leads to the mountain peak is not free of ambushes of thieves and lairs of wolves."

I wanted Yoda to be the traditional kind of character you find in fairy tales and mythology. And that character is usually a frog or a wizened old man on the side of the road. The hero is going down the road and meets this poor and insignificant person. The goal or lesson is for the hero to learn to respect everybody and to pay attention to the poorest person because that's where the key to his success will be.
