Obedience 

''When obedience becomes our goal, it is no longer an irritation; instead of a stumbling block, it becomes a building block.''

James E. Faust

I think that is true because in the world that we live in has many laws that we have to obey. When obedience comes there is no irritation because every thing goes right in its way. For example if you do the right thing, then the right will come to you. Another example is if you help, the help will come to you. In my opinion obedience is very important in today's life.
