What does Ecclesiastes 8:15 mean?

So I say, enjoy life. There’s nothing better for people than to eat, drink, and be glad. That’s what we get out of all our hard work during the days God gives us under the sun. Ecclesiastes 8:15 - Modern Text Bible

(Since life is unpredictable and often unfair, the writer encourages us to enjoy the simple pleasures—food, drink, and happiness—while we can.)
