As a youth, do not look down upon yourself because you are young, but continue keeping yourself pure through humility.
Do not let anyone look down upon you because you are young because what you carry is more than the way you look. This addresses everyone no matter their age, because there are people who have reached adulthood but still look down upon themselves. Humility is needed for one to remain a child and such a person is desired by God. Even adults who carry humility are children in the eyes of God.
