Bono explained: "I wrote the lyric based on the book of Ecclesiastes in the Old Testament, which in some translation is called The Preacher. It's a story of intellectual wanderlust. The preacher wants to find out the meaning of life and so he tries a bit of everything. He tries knowledge, educates himself, reads every book, but that doesn't do it. He tries travel, sees every sight, but that doesn't do it. He tries wine, women and song, that doesn't do it. All, he says, is vanity, vanity of vanities, striving after wind. As you read this book you think, 'I can't wait to hear what does do it!' And the most extraordinary line is: 'There is nothing better for a man, than that he should eat and drink, and that he should make his soul enjoy good in his labour.' Love your work. That's what it is. It is good to love what you do. I think there's a lot to that."
