Proverbs 17:20-22

New Catholic Bible

²⁰ One whose heart is perverse will never prosper,
    and one whose tongue is evil will come to trouble.
²¹ The father of a fool endures endless sorrow
    and receives no joy from having begotten him.
²² A cheerful heart^[a] is excellent medicine,
    but a crushed spirit dries up the bones.
