Aang:
But it's the Avatar's duty to master all of the bending disciplines

Jeong Jeong:
To master the bending disciplines you must first master discipline itself. But you have no interest in this, so I have no interest in you! Now, get out.

Aang:
Please, I have to learn. This could be my only chance

Jeong Jeong:
Are you deaf? How can I teach you if you refuse to listen? Before learning firebending you must learn water and earth. Water is cool and soothing, earth is steady and stable, but fire... Fire is alive, it breathes, it grows. Without the bender, a rock will not throw itself, but fire will spread and destroy everything in its path if one does not have the will to control it, THAT is its destiny! You are not ready! You are too weak!
