Obedience 

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

What david bednar is saying is that obedience is the center of becoming happy. The center of a good life. That obedience is the remaining to becoming happy. For example, if you listen to your mom you won't get mad and you will be happy. Another example is that you follow the rules and be a hard worker, respectful all that is just remaining to being happy.
