16. I said to myself, "Look, my wisdom has really been growing. In fact, I'm now wiser than anyone who ruled over Jerusalem in the past. I have a lot of wisdom and knowledge."
17. Then I used my mind to understand what it really means to be wise. And I wanted to know what foolish pleasure is all about. But I found out that that's also like chasing the wind.
18. A lot of human wisdom leads to a lot of sorrow. More knowledge only brings more sadness.
