\v 13 By using my wisdom, I concentrated on understanding everything that was being done on the earth. It is a task that wears me out, just like anyone else who tries it.
\v 14 It seems that nothing that happens on the earth really enables us to do anything useful. It is like trying to control the wind.

\v 15 Many things that are crooked cannot be caused to become straight.
\q2 We cannot count things that we cannot see.

\v 16 I said to myself, "I am wiser than any of those who ruled in Jerusalem before me. I am wiser and know more than any of them!"
\v 17 So I determined to learn more about being wise, and also to learn about doing things that are very stupid and foolish. But I found out that trying to understand those things was also useless, like trying to control the wind.
\v 18 Anyone who becomes very wise also becomes very frustrated. The more one knows, the sadder he becomes.
