The ONE Thing: The Surprisingly Simple Truth Behind Extraordinary Results

Gary Keller is the founder and chairman of the board of Keller Williams Realty, Inc., one of the largest and most successful realty companies in the world. Keller was born in Texas into a family of teachers. Early on, he had a great interest in music and planned to make a career in that field. However, he decided he needed a college education and was surprised to find out that his parents had already sent in an application to Baylor University for him. At Baylor, Keller became interested in studying real estate. He worked as a real estate agent after college, eventually founding the company Keller Williams Realty, Inc. with partner Joe Williams.

Keller grew the company rapidly by putting principles laid out in The ONE Thing into practice. However, he achieved this success only by first struggling. In his book, he describes how he once believed he was failing: Keller felt burnt out and thought that his management techniques were not conducive to success. Over time, Keller realized that focusing, prioritizing, and discovering purpose were key to achieving success and fulfilment. This realization came with major changes—including ending his role as CEO of Keller Williams.

Keller’s openness about his life and straightforward presentation of his principles emphasize that he is a reliable guide for readers who want to improve their focus, set priorities more effectively, and achieve success that aligns with their purpose. By discussing his struggles as well as his successes, Keller increases readers’ trust in his advice. In addition, Keller considers success in holistic terms, emphasizing that well-being, physical health, spiritual health, and family are fundamental priorities no matter your professional ambitions. He underscores this by writing about the importance he places on his own family and personal well-being.
