And I set my mind to know wisdom and to know madness and folly; I realized that this also is striving after wind.

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.

So I hated life, for the work which had been done under the sun was grievous to me; because everything is futility and striving after wind.

For to a person who is good in His sight He has given wisdom and knowledge and joy, while to the sinner He has given the task of gathering and collecting so that he may give to one who is good in God’s sight. This too is vanity and striving after wind.

I have seen that every labor and every skill which is done is the result of rivalry between a man and his neighbor. This too is vanity and striving after wind.

One hand full of rest is better than two fists full of labor and striving after wind.

There is no end to all the people, to all who were before them, and even the ones who will come later will not be happy with him, for this too is vanity and striving after wind.

What the eyes see is better than what the soul desires. This too is futility and a striving after wind.
