Proverbs 15:13-16

A merry heart maketh a cheerful countenance: But by sorrow of the heart the spirit is broken. The heart of him that hath understanding seeketh knowledge: But the mouth of fools feedeth on foolishness. All the days of the afflicted are evil: But he that is of a merry heart hath a continual feast. Better is little with the fear of the LORD Than great treasure and trouble therewith.
