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 
Obedience helps build us up. When we strive for obedience we'll stop getting irritated and it'll be something we're used to and what we're striving for. It won't be an obstacle or stumbling block, its a building block meaning it'll help us become a better person and obedience is something that'll help us go through life and grow. Obedience will be part of who we are if we make it a goal and reach it.
