'Accomplishments' in the Bible

I did not restrain myself from getting whatever I wanted; I did not deny myself anything that would bring me pleasure. So all my accomplishments gave me joy; this was my reward for all my effort.

Then I examined all of my accomplishments that I had brought about by my own efforts, including the work that I had labored so hard to complete and it was all pointless, like chasing after the wind, and there was nothing to be gained on earth.

I concluded that it is worthwhile for people to find joy in their accomplishments, because that is their inheritance, since who can see what will exist after them?
