Ecclesiastes 2:12

So I was great, and increased more than all who were before me in Jerusalem. My wisdom also remained with me.

Whatever my eyes desired, I didn’t keep from them. I didn’t withhold my heart from any joy, for my heart rejoiced because of all my labor, and this was my portion from all my labor.

Then I looked at all the works that my hands had worked, and at the labor that I had labored to do; and behold, all was vanity and a chasing after wind, and there was no profit under the sun.

Then I saw that wisdom excels folly, as far as light excels darkness.

The wise man’s eyes are in his head, and the fool walks in darkness—and yet I perceived that one event happens to them all.

Then I said in my heart, “As it happens to the fool, so will it happen even to me; and why was I then more wise?” Then I said in my heart that this also is vanity.
