Ecclesiastes 6:7-9

One Must Learn to Be Content with What One Has

7 All of a man's toil [is] for his mouth-- yet his appetite is never satisfied.
8 So do the wise [really] have an advantage over fools? {Can the poor [really] gain anything by knowing how to act in front of others}?
9 {Better to be content with what your eyes see than for your soul to constantly crave more}. This also [is] vanity and chasing wind!
