Plot summary

Danny Wallace, a freelance radio producer for the BBC in London, takes three simple words uttered by a stranger on a bus—"Say yes more"—as a challenge and says "yes" to everything for a year. He says "yes" to pamphleteers on the street, the credit card offers stuffing his mailbox and solicitations on the Internet. He attends meetings with a group that believes aliens built the pyramids in Egypt, says "yes" to every invitation to go out on the town and furthers his career by saying "yes" in meetings with executives.
