Yoda from the Star Wars films, had some very good wisdom, such as:

"Do or do not. There is no try."

"You must unlearn what you have learned."

"Named must be your fear before banish it you can."

"Fear is the path to the dark side. Fear leads to anger. Anger leads to hate. Hate leads to suffering."

"The greatest teacher, failure is."

And...

"Pass on what you have learned."
