Ecclesiastes 1:12 TLB

[12] I, the Preacher, was king of Israel, living in Jerusalem. And I applied myself to search for understanding about everything in the universe. I discovered that the lot of man, which God has dealt to him, is not a happy one. It is all foolishness, chasing the wind. What is wrong cannot be righted; it is water over the dam; and there is no use thinking of what might have been.
