Be yourself; everyone else is already taken.
God made you uniquely you. Do not change who you are to conform to this world. Find the courage to seek God's plan for you, the unique you that He created. His plan, not man's, is the perfect one for you.
Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.
