Ecclesiastes 2:10-11, 24

All that my eyes desired I did not refuse them. I did not withhold my heart from any pleasure, for my heart was pleased because of all my labor and this was my reward for all my labor. Thus I considered all my activities which my hands had done and the labor which I had exerted, and behold all was vanity and striving after wind and there was no profit under the sun.

There is nothing better for a man than to eat and drink and tell himself that his labor is good. This also I have seen that it is from the hand of God.
