Have you ever asked your parents something and they gave you a response that wasn't what you wanted them to say and you thought to yourself, "They don't know anything! I just want to have fun. Why don't they understand?!"
You then proceeded to do it anyways. Ever done that before? Pretty sure we're in the same boat, because I've done that a few times myself. At first, I felt I was being so independent and rebellious with my defiant stance! I soon came to realize all I did was lose the trust of my parents, felt awful about doing something wrong and lastly, I restricted myself even more from further opportunities.
We do the same thing with God's laws and His counsel at times. It's illustrated pretty well in the scriptures.
"Behold, they do not desire that the Lord their God, who hath created them, should rule and reign over them; notwithstanding his great goodness and his mercy towards them, they do set at naught his counsels, and they will not that he should be their guide."
When we "set at naught" the counsel and commandments we receive from God, we lose the light we once obtained and our lives begin to be filled with darkness. Our agency becomes limited and we have no promise from God.
Let us listen and obey and know that God is on our side and knows what is best for us!
