Roy Herbert Jarrett (1874–1937), author of the self-help classic It Works: The Famous Little Red Book That Makes Your Dreams Come True!, was a Chicago-based businessman whose motivational insights revolutionized early 20th-century personal development literature. A self-educated printing industry salesman, Jarrett distilled his success strategies into this concise 1926 guide, pioneering themes of positive affirmation, goal visualization, and subconscious mind programming decades before modern psychology popularized these concepts.
His seminal work has remained continuously in print for nearly a century and has been translated into multiple languages, including French and Spanish. Updated editions like It Works DELUXE EDITION and thematic companion pieces such as The Meaning of the Mark have expanded his legacy.
Jarrett’s pragmatic approach—emphasizing simple, actionable steps over theoretical frameworks—resonated with Depression-era readers and continues to influence contemporary self-help authors. The original text’s cult following persists through grassroots recommendations, with modern reprints frequently appearing on lists of influential personal growth literature. It Works has been credited by devotees for career transformations, creative breakthroughs, and lifestyle design successes across generations.
