Men are from Mars, Women are from Venus is a non-fiction book by American writer John Gray, first published in 1992. The book focuses on the differences between men and women, and how these differences can lead to misunderstandings and disagreements in romantic relationships.
Gray uses the metaphor of men are from Mars and women are from Venus to depict gender differences. He argues that men and women think, feel and communicate in different ways. Men, like Martians, focus on practical solutions and achievements. Women, like the people of Venus, focus on relationships and feelings.
