Ecclesiastes 6:7-9 - One Must Learn To Be Content With What One Has
7 All of man's labor is for nothing more than to fill his stomach -- yet his appetite is never satisfied!
8 So what advantage does a wise man have over a fool? And what advantage does a pauper gain by knowing how to survive? 9 It is better to be content with what the eyes can see than for one's heart always to crave more. This continual longing is futile -- like chasing the wind.
