'Accomplishes' in the Bible

I said of partying, "It is folly," and of self-indulgent pleasure, "It accomplishes nothing!"

For what does a person gain from everything that he accomplishes and from his inner life struggles that he undergoes while working on earth?

The only worthwhile thing for a human being is to eat, drink, and enjoy life's goodness that he finds in what he accomplishes. This, I observed, is also from the hand of God himself,

The more one argues with words, the less he accomplishes. How does that benefit him?
