Got to say something. It's in Proverbs somewhere. My favorite book in the Bible. It's what I told my grandkids to read first. It's what I tell everyone I meet when the Bible comes up. Anyways, in Proverbs you will find many verses which explains exactly this. Let the old man with wisdom teach the young man. Let the young man gain wisdom. Let those who refuse wisdom fall away. (paraphrasing here)
