Ecclesiastes 2:3, 17

I searched in my heart how to gratify my flesh with wine, while guiding my heart with wisdom, and how to lay hold on folly, till I might see what was good for the sons of men to do under heaven all the days of their lives.

Therefore I hated life because the work that was done under the sun was distressing to me, for all is vanity and grasping for the wind.
