"Obedience is central to becoming, being, and remaining happy." 

David Bednar 

For David the key to becoming, being, and remaining happy is obedience. Which means paying attention and always following directions. I guess he is really happy with life right now because he is always obedient. Always doing the right thing sure always makes us happy because we know we're doing the right thing. Perhaps being obedient is central to becoming, being, and remaining happy but i think finding yourself and knowing who you are is also central to becoming, being, and remaining happy. Also having freedom and not letting no one tell you how to be or how to dress because it's you and not them, and that your freedom.
