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 

Reflection: 

If being good was hard for you and now its not that means you've gotten use to doing good all the time. Like if it was hard for you to do something good for you neighbor like take out the trash for them because they were very old and it was very heavy for them. And, it was very hard foe them and they asked you to take it out and you did but you were very lazy but then you started getting use to it and it became a building block you no longer had an irritation to do it. And, now every day you take it out for them you don't complain  or anything because you've gotten use to it and now you do it everyday. That's what this quote means to me.
