Proverbs 23:22 Listen to your father– he who gave you life, and do not despise your mother when she is old.
The obvious reason is your father has more years of experience and wisdom, the same is true about your mother.
To ever think there is no value in the wisdom of your parents makes you a fool, because you will be, or are a parent. To despise your parents is to guarantee your children will despise you.
In youthfulness self confidence is rarely contained.
