Ecclesiastes 2:3, 17

I searched with my heart how to cheer my body with wine—my heart still guiding me with wisdom—and how to lay hold on folly, till I might see what was good for the children of man to do under heaven during the few days of their life.

So I hated life, because what is done under the sun was grievous to me, for all is vanity and a striving after wind.
