Ecclesiastes 2:15-19

Then I said in my heart, “What happens to the fool will happen to me also. Why then have I been so very wise?” And I said in my heart that this also is vanity. For of the wise as of the fool there is no enduring remembrance, seeing that in the days to come all will have been long forgotten. How the wise dies just like the fool! So I hated life, because what is done under the sun was grievous to me, for all is vanity and a striving after wind. I hated all my toil in which I toil under the sun, seeing that I must leave it to the man who will come after me, and who knows whether he will be wise or a fool? Yet he will be master of all for which I toiled and used my wisdom under the sun. This also is vanity.
