Ecclesiastes 2:3

2:3 I thought deeply about the effects of indulging myself with wine

(all the while my mind was guiding me with wisdom)

and the effects of behaving foolishly,

so that I might discover what is profitable

for people to do on earth during the few days of their lives.

Ecclesiastes 4:8

4:8 A man who is all alone with no companion,

he has no children nor siblings;

yet there is no end to all his toil,

and he is never satisfied with riches.

He laments, “For whom am I toiling and depriving myself of pleasure?”

This also is futile and a burdensome task!
