Ecc 1:16  I said to myself, "Behold, I have magnified and increased wisdom more than all who were over Jerusalem before me; and my mind has observed a wealth of wisdom and knowledge."

Ecc 1:17  And I set my mind to know wisdom and to know madness and folly; I realized that this also is striving after wind.

Ecc 1:18  Because in much wisdom there is much grief, and increasing knowledge results in increasing pain.
