[0] 2:11 [NIV] Yet when I surveyed all that my hands had done and what I had toiled to achieve, everything was meaningless, a chasing after the wind; nothing was gained under the sun. [The Voice] 
As I continued musing over all I had accomplished and the hard work it took, I concluded that all this, too, was fleeting, like trying to embrace the wind. Is there any real gain by all our hard work under the sun?
