'Accomplished' in the Bible

I decided to carefully and thoroughly examine all that has been accomplished on earth. I concluded: God has given people a burdensome task that keeps them occupied.

I reflected on everything that is accomplished by man on earth, and I concluded: Everything he has accomplished is futile -- like chasing the wind!

Yet when I reflected on everything I had accomplished and on all the effort that I had expended to accomplish it, I concluded: "All these achievements and possessions are ultimately profitless -- like chasing the wind! There is nothing gained from them on earth."
