Ecclesiastes 1:8

1:8 All this monotony is tiresome; no one can bear to describe it:

The eye is never satisfied with seeing, nor is the ear ever content with hearing.

Ecclesiastes 4:3

4:3 But better than both is the one who has not been born

and has not seen the evil things that are done on earth.

Ecclesiastes 5:10

Covetousness

5:10 The one who loves money will never be satisfied with money,

he who loves wealth will never be satisfied with his income.

This also is futile.
