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

This quote is trying to say that if you are obedient, you will be happy. If you obey the rules, choose the right, do well, you will receive freedom, and freedom is Happiness.
For Example: If you obey the home rules, your parents will let you the freedom to go to parties, and in the parties you are happy.
