Men Are from Mars, Women Are from Venus (1992) is a book written by American author and relationship counselor John Gray, after he had earned degrees in meditation and taken a correspondence course in psychology. The book states that most common relationship problems between men and women are a result of fundamental psychological differences between the sexes, which the author exemplifies by means of its eponymous metaphor: that men and women are from distinct planets—men from Mars and women from Venus—and that each sex is acclimated to its own planet's society and customs, but not to those of the other. One example is men's complaint that if they offer solutions to problems that women bring up in conversation, the women are not necessarily interested in solving those problems, but mainly want to talk about them. The book asserts each sex can be understood in terms of distinct ways they respond to stress and stressful situations.
The book has sold more than 15 million copies and, according to a CNN report, it was the "highest ranked work of non-fiction" of the 1990s, spending 121 weeks on the bestseller list.The book and its central metaphor have become a part of popular culture and the foundation for the author's subsequent books, recordings, seminars, theme vacations, one-man Broadway show, TV sitcom, workout videos, a podcast, men's and ladies' apparel lines, fragrances, travel guides and his-and-hers salad dressings.
