Ecclesiastes 1:14-18

I examined everything people do here on earth, and discovered that it's all so temporary—trying to understand it is like trying to pin down the wind!

You can't straighten what is twisted, and you can't count what isn't there.

I thought to myself, “I've become very wise, wiser than all the kings of Jerusalem before me. My mind has gained a great deal of wisdom and knowledge.”

So I decided to use my mind to learn everything about wisdom, and madness and foolishness as well. But I found out that this is as hard as trying to catch hold of the wind.

For with great wisdom comes great frustration. The greater the knowledge, the greater the pain.
