You're thinking too hard.

[Wan lifted a hand to place it lightly on Zuko's chest, over his heart.]

Do what feels right in here. That's the best place to start.

[He dropped his hand and straightened up.]

You'll still make mistakes. Everyone does. I did. I still do. But you can't be afraid of that. You can't be afraid of things not always making sense. If you start with what feels right in your heart, you'll eventually find your way.
