Writing career 
Rath’s first book, How Full Is Your Bucket?, coauthored with his grandfather,  Donald O. Clifton, during his final year of life, became a New York Times bestseller in 2004. The book aims to teach children the value of "filling your bucket" and that people should also value every moment. Strengths Based Leadership (2009), co-authored with Barry Conchie, is based on Rath’s and Gallup's research on leadership and on what followers expect from their leaders (trust, compassion, stability, hope). Wellbeing: The Five Essential Elements (2010), a New York Times bestseller, coauthored with Jim Harter, is based on Gallup’s research on wellbeing. The book lists five elements of well-being: career well-being, social well-being, financial well-being, community well-being, and physical well-being. Rath’s most well-known book, StrengthsFinder 2.0 (2007), a #1 Wall Street Journal bestseller, was listed as the top worldwide business bestseller by The Economist in 2011. It suggests that employees and employers should develop their unique skills rather than spend time improving their weaknesses. Eat Move Sleep 

At the age of 16, Rath was diagnosed with VHL disease, a rare genetic disorder that causes cancer cells to appear in various parts of the body. Since the time of the diagnosis, Rath has been researching and experimenting with various ways of slowing down the growth of tumors in his kidneys, adrenal glands, pancreas, and spine. In 2012, he took a sabbatical from his full-time position in Gallup to focus on writing a new book, titled Eat Move Sleep: How Small Choices Lead to Big Changes which became a New York Times bestseller upon its publication in October 2013. Eat Move Sleep was also recognized as one of the best nonfiction books of 2013 by Apple iTunes. It describes the impact of eating, moving, and sleeping on health and everyday energy and offers practical ideas on how to make better health choices. The book emphasizes the interrelatedness of eating, moving, and sleeping and encourages focusing on all three in any health improvement program. Publications, a selection
