Ecclesiastes 6:7-9 - One Must Learn To Be Content With What One Has
7 Every person works for his own self-interests, but his desires remain unsatisfied.
8 For what advantage has the wise person over the fool? What advantage does the poor man have in knowing how to face life? 9 It is better to focus on what you can see than to meander after your self-interest; this also is pointless and a chasing after wind.
