The ruin of the young is either living by no rule at all, or choosing false rules.
Psalms 119:12-17 Be blessed, God; train me in your ways of wise living. I’ll transfer to my lips all the counsel that comes from your mouth; I delight far more in what you tell me about living than in gathering a pile of riches. I ponder every morsel of wisdom from you, I attentively watch how you’ve done it. I relish everything you’ve told me of life, I won’t forget a word of it. Be generous with me and I’ll live a full life; not for a minute will I take my eyes off your road.
