Ecclesiastes 2:20-23

²⁰I thought about all the hard work that I had done. It seemed useless, and I became depressed/discouraged.

²¹Some people work wisely and skillfully, using the things that they have learned. But when they die, they leave everything, and someone who has not worked hard acquires those things. And that also seemed to be senseless and caused me to be discouraged.

²²So, it seems that people do not RHQ get much for all the hard work that they do and for worrying.

²³Every day the work that they do causes them to experience pain and to be worried. And during the night, their minds are not able to rest. That also is very frustrating.
