Ecclesiastes 1:16-18 New Century Version (NCV)

16. I said to myself, “I have become very wise and am now wiser than anyone who ruled Jerusalem before me. I know what wisdom and knowledge really are.”

17. So I decided to find out about wisdom and knowledge and also about foolish thinking, but this turned out to be like chasing the wind.

18. With much wisdom comes much disappointment;the person who gains more knowledge also gains more sorrow.
