"When obedience becomes our goal, it is no longer an irritation; instead of a stumblinng block, it becomes a building block."- James E. Faust  

What james is trying to say is to obey because your goal is to obey. obedience should always be your goal because because it brings good to you. and obeying shoudn't irritate you because you suppose to obey. ones you start to obey it isnt going to irritate you no more its actually going to make you feel good.and instead of stumbling in a block you have to build a wall. that mean that instead of stumbling you should obey and build a wall with your obedience.  so always obey and do good things. always make your self grow with your obedience. obedience makes you grow. so obedience shoudl be one of your goals.
