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

This quote is saying that when you choose to do the right things it becomes your goal and once it becomes your goal you make it even better and you don't let it go down. It doesn't matter how much you work for it or how much you stress over it all that matters is that you accomplished it and you're happy with it. When you accomplish you goals and you do it with obedience that's what makes yourself better and make you want to do better. If you obey and do what you need to do then do it because that may be your goal, to obey and feel good about yourself. For example, if you have a goal to make someone happy or do something nice for someone and you do it because you want to and obey whatever there is to do then you accomplished your goal. You want to strive to do best and obey because that's the best way to accomplish your goals. If you set your mind to your goals and do them the right way then you will get what you want and the way you want it to be. Accomplish your goals the way you want to accomplish them because nobody else will do it for you and won't do it the way you want it to be.Obedience is what you need to do in order to get what you want. Always be the best person you can be and be obedient for other people but mostly for yourself.
