Proverbs 15:13-15 AMP
A heart full of joy and goodness makes a cheerful face,
But when a heart is full of sadness the spirit is crushed.
The mind of the intelligent and discerning seeks knowledge and eagerly inquires after it,
But the mouth of the [stubborn] fool feeds on foolishness.
All the days of the afflicted are bad,
But a glad heart has a continual feast [regardless of the circumstances].
