W. Timothy Gallwey

W. Timothy Gallwey is the author of the "The Inner Game" book series and the founder of the company of the same name, which applies the principles and methods of the inner game for personal development and professional excellence across a wide range of activities. He was born in 1938 in San Francisco. As a teenager, he achieved a high ranking in the U.S. tennis championship and later studied tennis at Harvard University, where he also took on the role of coach for the university team. In the 1970s, his interest shifted to sports psychology and the study of improving tennis players' performance through concentration and focus. Alongside his coaching career, he began taking notes that would eventually become the material for his first book, "The Inner Game of Tennis," a kind of Bible for tennis players (2,500,000 copies sold in the U.S. alone). Shortly after the book's initial release, companies such as Apple, AT&T, Coca Cola, and Rolls Royce sought Gallwey's assistance to improve the performance of their executives in personnel management, team organization, sales, and entrepreneurship. Other works by him include: "The Inner Game of Work," "The Inner Game of Music," "The Inner Game of Golf," and "The Inner Game of Stress."
