Much labor wearies the body
and many thoughts oppress the mind:
Man aimes at profit by the one
And content in the other;
But often misses both,
And find nothing but vanity and vexation of spirit.
Then I looked on all the works that my hands had wrought, and on the labour that I had laboured to do: and, behold, all was vanity and vexation of spirit, and there was no profit under the sun.
